The reservoir is a tank in which an adequate supply of fluid for the system is stored. Fluid flows from the reservoir to the pump, where it is forced through the system and eventually returned to the reservoir.

Hydraulic Oil Tank

The system reservoir hold enough fluid for use in operation of the system and to replace fluid lost through minor leakage or evaporation. Reservoirs may also be Installed to provide a space for increase in fluid volume over the original amount, such as that which might occur through thermal expansion or foaming They also provide a place of escape for air trapped in the system.

The Directional Control Valve is a 3-Way, 2-Position spool sleeve valve that is normally biased control (C1) to return (RTN). The valve is commanded to route flow/pressure from the PRS port to C1 by energizing a 28 Vdc nominal solenoid.

Directional Control Valve

This Engine Driven Pump is a variable displacement pump which extracts mechanical power from the gearbox accessory pad and converts it into hydraulic power available for use by the various actuators and other consumers on the AH-64 Apache aircraft. The maximum displacement of the pump is 0.182 CIPR and it is capable of providing 6 gpm of flow.

Engine Driven Pumps

This hydraulic motor (also known as “Hydrive”) is a bi-directional, fixed displacement axial piston device which extracts energy from high pressure hydraulic fluid and transforms it into torque available at the output shaft. It is used on the General Dynamics Ordnance and Tactical Systems (GD-OTS) JSF gun system.

Hydraulic Motor

Fuel flow transmitters measure the flow rate of fuel through the component. As more fuel is flowed, more torque is applied to a turbine assembly. This torque creates distance between two magnetic pick-off’s which in turn creates distance between the electrical signal generated. The electrical signal is interpreted by a computer and a fuel flow rate is calculated.

Fuel Flow Transmitter

The Hydraulic Start Motor is used to provide the output torque and shaft speed required for starting the V-22 Tiltrotor Aircraft main engines. The starter is comprised of a variable-displacement hydraulic motor with an integrally housed flow control valve and sprag clutch.
