摘要： A pump system having a main pump and a plurality of subsidiary pumps each of which has a relatively low pressure compartment from which fluid may be pumped to a relatively high pressure compartment. The main pump preferably operates continuously, but each of the subsidiary pumps is inactive until such time as it is elected to be operated, whereupon high pressure fluid from the main pump may be directed to such subsidiary pump. The pump system is particularly adapted for use in conjunction with an automotive engine.

摘要： A reinforcing structure for a member such as a truck bed comprises an elongate, trough-like body having side walls diverging from a base and terminating at their free ends in outwardly turned mounting flanges. Fixed to the base and extending therefrom between the body side walls is an elongate strut the height of which corresponds to that of the side walls. Spanning the distance between the strut and each side wall is a plurality of spaced apart ribs, the upper edges of which are flush with the strut and flanges. The side walls of the body may have a thickness less than that of the strut which, in turn, may have a thickness less than that of the ribs.

摘要： A coupling for use in a vehicle having an extensible and retractable ram reacting between the vehicle frame and a rockable dump body for raising and lowering the latter comprises a pair of parallel links straddling the ram and being pivoted at corresponding ends to the body and at their opposite ends to the ram. The pivotal connection of the links to the body preferably is of the ball joint type to enable substantially universal movement of the links relative to the ram. The coupling enables limited relative movement between the body and the vehicle frame without necessitating extension and retraction of the ram.
