Abstract
A hydraulic coupling (32,32a) includes a lock (204) for selectively preventing the level of torque transmitted from a coupling casing (34) to a pair of rotary members (26,28) from affecting torque transfer between the rotary members. The coupling (32) also includes an adjuster (216) for adjusting resistance of fluid flow from a hydraulic pump (48) through ports of the coupling to control coupling of the pair of rotary members (26,28) to each other. One embodiment of the coupling (32) operates in a supercharged pumping manner, while another embodiment of the coupling (32a) pumps the fluid through a clutch actuating piston (72) of the coupling.
