    Abstract: A piston-type accumulator in a hydraulic circuit is provided with an interior sleeve proximate the gas valve for limiting piston movement and providing a minimum predetermined accumulator gas volume. By monitoring the pressure of the gas charge in the minimum predetermined gas volume, it may be determined whether the accumulator retains sufficient energy for proper operation in the hydraulic circuit or requires recharging.

    Abstract: A piston type gas-liquid accumulator wherein a maximum of displaceable fluid volume is attained by providing an auxiliary piston within a hollow main piston, the auxiliary piston being mounted on a rod in the main piston and movable from one end of the main piston to the other for alternately displacing gas and liquid from the hollow main piston.

    Abstract: The accumulator disclosed herein has a spring, which consists of two or more concentric steel cylinders with at least one cylinder sleeve of neoprene between them. The contact surfaces of the steel and the neoprene are bonded together and have a shear strength equal to the shear strength of the neoprene itself. The inner cylinder is connected to a piston rod and the outer cover encloses the assembly. The length of the space is such that sufficient preload is placed on the assembly to hold the parts together, even under shock conditions. A manifold connecting a relief valve and a check valve with the appropriate passages and porting is attached to the side of the cylinder, permitting the passage of oil into and out of both ends of the cylinder.

    Abstract: A piston accumulator for hydraulic actuators, presses or the like is formed with a plunger piston for reciprocating within gas and liquid receiving chambers which are sealed and separated from each other in such an effective manner that compressed air rather than nitrogen may be used in the gas chamber without the danger of ''''dieselization.'''' The plunger piston is guided and sealed by a piston and guiding means intermediate the liquid and gas chamber rather than by usual cylinder bore walls. The expense of machining such internal cylinder bore walls is eliminated as well as the problem of leakage caused by scoring and scratching such machined cylinder bore walls by spacing the chamber walls from the piston plunger wall and using a soft bearing material for the piston sealing and guiding means into which dirt or other material may embed. Means are provided for varying pressure and/or volume of gas to achieve various operating characteristics for the hydraulic press.

    Abstract: An arrester for inhibiting hammer caused by interruption of fluid flow in conduits comprises a hollow cylindrical body closed at one end and open at the other. A piston is freely slidable within the body forming with the closed end thereof an hermetically sealed gas chamber. A connector connects the open end of the body with the conduit conveying fluid under pressure. Under fluid hammer conditions, the piston is advanced against the gas in the gas chamber. This forms a cushion which absorbs the shock and prevents the development of fluid hammer.
