control elements
From what has been previously discussed, electrical control
elements have the following advantages over the hydro-
mechanical valves:
• Controllability: because of the digital control capabilities,
electrical control elements perform expanded,
reprogrammable and smarter control functions than
hydro-mechanical valves.

• Closed-Loop Control: hydro-mechanical components can’t
be used to build closed loop control system with electrical
feedback. They can perform limited closed control with
mechanical feedback such as in pressure compensated,

Under other respects, this hydraulic generator is more similar
to standard internal gear pumps (see next paragraph), yet
it cannot fall into this category because it does not have a
component known as ‘prefill’ and it has much lower working
pressures.
This component, referred to as ‘low-pressure internal gear
pump’ in manufacturer catalogues, is characterised by a
peculiar innovation. An insert made of a deformable material
is embedded in the external part of each tooth of the
peripheral wheel; the insert balances the tolerance between
the teeth of the ring wheel and the central wheel solidly
connected to the transmission shaft, thus ensuring a firm
tightness between suction and delivery chambers (Figure

Screw pumps are better then external gear pumps in some

The centrifugal force is not enough to set vanes into motion

depending on the materials and the design; the adhesion
force of the vanes to the stator affects their life at a rotational
speed above 2500 rpm.
In any case, the centrifugal force alone cannot guarantee
a high efficiency, especially at rather low speeds (around
800-1000 revolutions). Vanes adhere to the eccentric stator
thanks to the pressurised oil sent to their back head through
a clearance inside the rotor that connects the outlet to the
vane seats. During the inlet the vanes cause a vacuum that
sucks the fluid from the tank, while during the delivery the
liquid is sent to the outlet.
Figure 4.25
Balancing is not problematic because the pressurised fluid
in motion fills the interstices between the screws and the
pump casing, thus generating compensating radial forces;
the translation is axial and the fluid found between the rotors
avoids friction. A very accurate design of threads prevents the
fluid from being squeezed between the parts in mesh (see
gear pumps) and it also ensures the most constant flow rate
among volumetric pumps; the slight pulsating flow virtually
results from the compressibility of the liquid inside the outlet.

Fixed displacement vane pumps 4.27. If the vertex was in the opposite direction, fluid pressure
would act on the vane end pushing it towards the seat.
Fixed displacement vane pumps are popular among many
self-propelled machines manufacturers and widely used
in medium-power stationary applications because of their
design simplicity, good value for money, reasonable efficiency
and the ability of balanced versions to reach higher average
pressures than other rotary pumps.

Figure 4.31
Figure 4.28 Vane pumps are usually set to rotate clockwise. Depending
on the manufacturer (the revolution is usually limited by
the position of the pins), anticlockwise revolution occurs
by rotating the unit made up of vanes, stator and rotor (the
direction of the revolution in all types of pump is viewed by
the shaft end).

and as many inlets. In this manner, the radial forces acting
on an outlet are offset by the forces acting on the other
(Figures 4.30 and 4.31). As a result, the hydraulic thrust
counterbalance most of the radial unbalance and it promotes
the dimensioning reduction of bearings.
Figure 4.33
Bushes and heads, found on both sides of the rotor/stator
unit, guarantee an adequate suction/distribution of the fluid
and the axial balance of the system.
In particular, brass intermediate bushes or wear plates, as
well as distribution slots, distribute through splines the thrust
fluid over the bases of each vane and (in pin or intravane
vanes – see later on) in their clearances. The pressurised fluid
flows into the two basins, fitted with proper seals and an anti-
extrusion ring, in the internal parts of the pressure plates,
that channel it into the splines of the bushes (Figure 4.34).
Figure 4.30

Unlike the pressure in the fluid film between the bushes and
the rotor/stator unit, the pressure in these basins offsets the
pump axial loads.

In everyday language, standard pumps with single inlet and
outlet are referred to as ‘round’ and radially balanced pumps
as ‘square’ (Figure 4.35) due to their shape.
Figure 4.37
Vanes must be balanced in order to ensure high performances.
An effective system consists in putting double vanes with
opposed sharp edge in the slots (Figure 4.36). The tightness
between vanes and the stator virtually doubles and, in
order to reduce the ensuing friction, opposite cavities are
manufactured on the sides so that the pressurised fluid flows
through them and, only in the delivery area, it offsets stator
pressure.
Figure 4.38
The pressure at the base of the vane in intravane systems
(Figure 4.37) depends on its positioning: the base of the
vane is alternately subjected to suction and delivery pressure
during the revolution. The slot between the small insert and
Figure 4.35 the vane is constantly subjected to delivery pressure.
The fluid is routed to the base of the vane through small
double clearances between its seatand the external part of
the rotor (Figure 4.38 – A e B –). The constantly pressurised
fluid flows to the cavity between the insert and the vane via
a clearance between the slot and the plane face of the rotor
(Figure 4.38 – C –), which is routed by the wear plate. The
insert, driven by the pressurised fluid to the ring, does not
move in the lower part of the slot.
In single vane pumps, the thrust fluid at the base of each
vane is always at delivery pressure. This ensures an optimum
tightness, but it also results in a strong friction on the stator

These particular types of hydraulic generators can also be

the pump can be started with a fluid viscosity of 800 cSt, with
appropriate precautions recommended by manufacturers,
like initial low speed. Obviously, under these conditions the

variable displacement vane pumps
Variable displacement vane pumps are based on the same
operating principle as fixed displacement pumps and they are
the type of pumps whose flow rate best adapts to the system
requirements. The balancing systems previously described
can be applied to variable displacement pumps only to a
limited extent, therefore efficiency and working pressures
drop dramatically. Virtually, these pumps are similar to the
obsolete fixed round pumps, but they differ in the obliquely

Some fundamental steps must be taken in order to install
the pump in the tank correctly. As many manufacturers
recommend, it is advisable to position it with the controller
placed upward (see Figure 4.48); motor pumps are usually
mounted below the fluid level in high-flow and high-pressure
systems. The drainpipe must not be connected to the output
hose, but directly to the tank, away from the inlet and below
the minimum level in order to prevent foam from forming.
Figure 4.48
Besides the measures on shaft alignment and antivibration
plugs that have already been described, other actions should
be taken, like adding an air bleed and, after the installation,
prefilling the pump via the drain hole (Figure 4.49).

theory the pressure is maximum, the flow rate is zero and
little power is absorbed, that is as much power as it is needed
to keep the rotor/vanes unit sliding and overcome internal
resistances. Actually, there is no flow in the user circuit, but
it continuously circulates throughout the pump. The fluid

The typical stationary application of variable displacement
pumps is on machine tools that require pressures of about 120
