The present disclosure provides an actuation mechanism for applying a mechanical diode clutch. The actuation mechanism includes a capsule including a cylindrical body defining an interior chamber, the cylindrical body defining a first opening at a first end and a second opening at a second end thereof. The actuation mechanism also includes a pin having a body and a radially-extending arm, the pin being retained within the interior chamber of the capsule. An apply spring is coupled at one end to the pin and a return spring is retained within the interior chamber of the capsule. The return spring is disposed between the pin on one end and the cylindrical body on the opposite end thereof. The return spring substantially surrounds the apply spring.

An engine clutch device includes first and second alternately stacked frictional power transmitting members and a clutch pressure member for axially bringing the frictional power transmitting members into pressure contact. The clutch device includes an oil supply portion adjacent to a distal end of power transmission shaft. The clutch device has an oil supply structure including a clutch lifter member with a flange portion axially facing the distal end of power transmission shaft, to axially shift the clutch pressure member to release the pressure contact of the frictional power transmitting members. The flange portion has a bowl-shaped portion extending axially to surround the one end portion of the power transmission shaft. The bowl-shaped portion including the flange portion functions to guide oil axially inward along the power transmission shaft and serves to provide an improved oil supply effect to the frictional power transmitting members.

A hydraulic pump with an integrated clutch includes an outer cone coupled to a drive gear or a driven gear and having a frictional inner surface, and an inner cone arranged inside the outer cone, coupled to the drive gear or the driven gear and having a frictional outer surface, wherein the inner and outer cones are rotationally and axially movable with respect to each other. A spring is coupled to the inner cone or the outer cone and acts to axially displace the inner cone with respect to the outer cone in a first direction. An actuator including a rod and a piston is coupled to the inner cone or the outer cone and acts to overcome the force of the spring to axially displace the inner cone with respect to the outer cone in a second direction being axially opposite to the first direction.

A clutch mechanism includes a transmission shaft, driven by an output shaft of a motive power device; a clutch element, including an engagement end, in unidirectional transmission connection with the transmission shaft, and a meshing end; a push rod, passing through the clutch element and including a contact end and a fixed end connected to the transmission shaft; a gear shaft, including a transmission gear in transmission connection with the meshing end; a rotary element, surrounding the gear shaft in a rotatable fashion and including a transmission end and a drive end; and a restoring element, one end bearing against the transmission shaft and another end bearing against the output shaft; and a drive gear, in transmission connection with the gear shaft and provided in a circumferential direction with a drive portion capable of pushing the transmission end. A gas insulated circuit breaker including clutch mechanism is also disclosed.

A clutch apparatus includes a clutch outer, a clutch inner, driving friction plates, driven friction plates, a pressure receiving plate, a pressing plate, a movable cam member, a fixed cam member, clutch springs, and a swollen portion.
