摘要： A gas spring (10) for forming equipment, including a piston (12) received at least partially in a cylinder (14) for reciprocation between extended and retracted positions, and including a throttling passage (94) disposed between the piston (12) and the cylinder (14) in fluid communication between first and second pressure chambers (16,18) during at least a portion of the reciprocation of the piston (12). The throttling passage (94) is of variable cross-sectional area, which varies with a length of the passage (94) to at least partially restrict gas flow therethrough in a manner varying with return of the piston (12) toward its extended position to decelerate the piston (12) at a predetermined rate.

摘要： A hydraulically-operated press-driven tool actuation system includes a press-driven hydraulic power device (100) and/or a hydraulically-powered tool actuator. In the tool actuator, at least two pistons are carried by a housing, and at least one return device is carried by the housing laterally inboard of the pistons. In the power device, a pump (102) includes a piston disposed in a pump cylinder for pressurizing hydraulic fluid therein. An accumulator (104) is in fluid communication with the pump cylinder, and includes a piston disposed in an accumulator cylinder that houses hydraulic fluid on one side of the piston. A body (106) supports the pump (102) and accumulator (104) thereon and is in fluid communication between the pump and accumulator cylinders. The body (106) includes a pressure relief valve downstream of the pump cylinder and upstream of the accumulator cylinder, and a check valve downstream of the accumulator cylinder and upstream of the pump cylinder.
