n: a device for changing alternating current to direct current or vice versa;usually, if the device changes AC to DC, it is called a rectifier.

n: in a hydraulic coupling or torque converter, the moving fluid that impinges against blades to move the member being driven.

n: an electronic instrument for converting frequency (pulse train) to a proportionate analog signal.

n: see hydraulic coupling.

n: an hydraulic drive assembly that can self-adjust speed according to the load.

n: an hydraulic drive assembly that can self-adjust speed according to the load.

n: see converter.

n: clutches and gears used with an engine for automatically and smoothly changing power ratios. The device is usually used in conjunction with a hydraulic torque converter.

a chemical that converts an acid insoluble scale to a acid soluble material.

n: a hydraulic device connected between an engine and a mechanical load such as a compound. Torque converters are characterized by an ability to increase output torque as the load causes a reduction in speed. Torque converters are used on mechanical rigs that have compounds.

n: It be setted between the engine and drive mechanism,which can increase the torque when velocity decline caused by loading increasing.
