310-3000 IHT 33

Hydrostatic Transaxle: A multicomponent as sem bly including a gear case and a hydrostatic

trans mis sion.

Hydrostatic Transmission: The combination of a hy drau lic pump and motor in one housing to

form a de vice for the control and transference of power.

Inlet Line: A supply line to the pump.

Integrated Hydrostatic Transaxle (IHT): The com bi na tion of a hydrostatic transmission and

gear case in one housing to form a complete transaxle.

Manifold: A conductor which provides multiple con nec tion ports.

Neutral: Typically described as a condition in which ﬂ uid ﬂ ow and system pressure is below that

which is required to turn the output shaft of the motor.

Pressure Decay: A falling pressure.

Priming: The ﬁ lling of the charge circuit and closed loop of the ﬂ uid power system during start

up, fre quent ly achieved by pressurizing the ﬂ uid in the inlet line.

Purging: The act of replacing air with ﬂ uid in a ﬂ uid power system by forcing ﬂ uid into all of the

com po nents and allowing the air a path of es cape.

Rated Flow: The maximum ﬂ ow that the power sup ply system is capable of maintaining at a

spe ciﬁ c op er at ing pressure.

Scoring: Scratches in the direction of motion of me chan i cal parts caused by abrasive con tam i-

nants.

Swash Plate: A mechanical device used to con trol the displacement of the pump pistons in a

ﬂ uid power sys tem.

System Charge Check Valve: A valve con trol ling the replenishing ﬂ ow of ﬂ uid from a charge

circuit to the closed loop in a ﬂ uid power system.

System Pressure: The pressure which over comes the total resistance in a system, in

clud ing

all losses.

Valve: A device which controls ﬂ uid ﬂ ow di rec tion, pressure, or ﬂ ow rate.

Variable Displacement Pump: A pump in which the displacement per cycle can be varied.

Volumetric Displacement: The volume for one rev o lu tion.
