A handle, fixedly mounted to one end of the lock bolt causes the sliding of the lock bolt through the intermediary of a rotary cam and pin follower, which pin follower, in the raised cam land position, against the bias of the springs, holds the frusto-conical portion in the selected frusto-conical receptacle.

Abstract: A hose end coupling unit which has an expandable interlocking snap ring interconnecting a plug member inside a socket member. The interlocking snap ring has a countersunk or funnel-shaped mounting hole, which fits over a frusto-conical cam surface on the plug member and is expanded thereby, as the plug member is inserted into the socket member, into an internal groove within the socket, and is held in an expanded state confined in the groove, after passing over the cam surface, on a cylindrical shoulder portion on the plug member. A spacer snap ring nested in an external groove in the plug member, outside the socket member, prevents the plug member from being inserted deeper into the socket member once the interlocking snap ring is seated on the shoulder portion. An O-ring seal at the entrance of the socket member seals the interconnected plug and socket members.

Abstract: A hydraulic control device for use in a hydraulic system having a pump supplying fluid from a reservoir to a working circuit. The control device detects leaks in the working circuit by monitoring the level of hydraulic fluid in the reservoir. In the event of a drop in the level of hydraulic fluid beyond a predetermined low level, the control device automatically diverts the fluid output side of the pump to the fluid input side to prevent further loss of fluid in the working circuit and to safeguard against cavitation in the pump due to the low level of fluid in the reservoir. The control device also senses excessive pressure peaks in the working circuit and operates to relieve the excessive pressure peaks by automatically venting a portion of the fluid on the output side of the pump to the reservoir.
