Definitions:

Non-Positive Displacement

A type of pump or motor wherein the fluid or gas flow rate does not have a direct correlation with the speed of the moving parts, allowing for variable output.

Engine Coolant Pump

A pump, also known as a water pump, that circulates coolant through an engine's cooling system to regulate its temperature and prevent overheating.

Plunger

A device that uses a movable rod to create suction or pressure, commonly used in pumps, valves, and hydraulic systems.

Swash Angle

The angle of the swash plate in a hydraulic pump or motor, which controls the displacement and direction of fluid flow, affecting the output speed and torque.
