ABSTRACT:
Disclosed is a fluid coupling which includes: a housing being used as a rotary driving member; a rotor rotatably mounted in the housing and being used as a driven member, a fluid pump having a pump chamber defined between the housing and the rotor; a fluid inlet port and a fluid outlet port; and a fluid circulation passage between the chamber and the housing, such that fluid in the pump circulates from the fluid circulation passage into the pump chamber through the inlet port and from the pump chamber through the outlet port into the fluid passage. The fluid coupling further includes: a fluid lock mechanism consisting of a cylinder bore provided in the housing such that the axis of the cylinder bore is in the radial direction of the coupling; a governor-weight sealingly and slidingly disposed in the cylinder bore; a spring for urging the governor-weight in the radially inward direction; a first opening provided at the radially inward portion of the cylinder bore, and; a second opening provided at the side wall portion of the cylinder bore. The first and second openings are provided in the fluid circulation passage which communicates the fluid inlet port with the fluid outlet port.
