Hydraulic Motor:
A device that converts hydraulic
fluid power into mechanical force and motion by
transfer of flow under pressure.
Hydraulic Pump:
A device that converts mechani-
cal forces and motion into hydraulic fluid power by
producing flow.
Hydrostatic Pump:
See “Hydraulic Pump”
Hydrostatic
Transaxle:
A
multi-component
assembly including a gear case and a hydrostatic
transmission.
Hydrostatic Transmission:
The combination of a
hydraulic pump and motor in one housing to form a
device for the control and transference of power.
Inlet Line:
A supply line to the pump.
Integrated Hydrostatic Transaxle (IHT):
The
combination of a hydrostatic transmission and gear
case in one housing to form a complete transaxle.
Manifold:
A conductor that provides multiple con-
nection ports.
Neutral:
Typically described as a
condition in
which fluid flow and system pressure is below that
which is required to turn the output shaft of the
motor.
Pressure Decay:
A falling pressure.
Priming:
The filling of the charge circuit and closed
loop of the fluid power system during start up, fre-
quently achieved by pressurizing the fluid in the
inlet line.
Purging:
The act of replacing air with fluid in a flu-
idpower system by forcing fluid into all of the com-
ponents and allowing the air a path of escape.
Rated Flow: The maximum flow that the power
supply system is capable of maintaing in at a spe-
cific operating pressure.
Scoring: Scratches in the direction of motion of
mechanical parts caused by abrasive comtami-
nants.
Swash Plate: A mechanical device used to control
the displacement of the pump pistons in a fluid
power system.
System Charge Check Valve: A valve controlling
the replenishing flow of fluid from a charge circuit
to the closed loop in a fluid power system.
System Pressure: The pressure that overcomes
the total resistance in a system, including all
losses.
Valve: A device that controls fluid flow direction,
pressure, or flow rate.
Variable Displacement Pump: A pump in which
the displacement per cycle can be varied.
Volumetric Displacement: The volume for one
revolution.
