摘要： A hydraulic accumulator has a chamber divided into compartments by a slidable member and a bellows. The bellows is provided at its outer and inner edges with axially extending portions which nest together when the bellows is compressed by discharge of hydraulic fluid from one of the compartments, whereby relative lateral movement of the bellows segments is prevented.

摘要： An automatic precharge gas pressure adjuster for a hydraulic desurger for automatically adjusting the precharge gas pressure in response to operating changes in system fluid pressure thereby maintaining a constant volume of precharge gas in the desurger. The adjusting unit comprises a cylinder divided into two chambers by a spring-biased differential-area piston. The system fluid pressure communicates with the chamber facing the first or largest area piston face while precharge gas communicates with the chamber facing the second or smallest area piston face. To assure the precharge gas pressure will be adjusted for changes in system operating pressure only, and not for mere surges, snubbing restrictions are placed in the means connecting the hydraulic system with the precharge gas adjusting unit.

摘要： The diaphragm chamber-damping device has a dished shell below the diaphragm which cooperates with a separating wall to form a pair of chambers within the liquid compartment while providing for a flow of fluid between the two chambers. One chamber communicates with an inlet pipe while the other chamber communicates with an outlet pipe so that fluid can be passed through the device.

摘要： An upper gas chamber and a lower pressure fluid chamber separated from each other by a diaphragm deflectable in direction of the gas chamber in response to pressure fluid admitted into the lower chamber. The diaphragm comprises a peripheral portion which, by means of an annular element, is sealingly pressed against the inner wall of the reservoir. The annular element has an arcuately curved circumferential guide surface which faces towards the fluid pressure chamber such that upon admittance of a fluid pressure in this latter chamber the center portion of the diaphragm is deflected into the gas chamber whereby the peripheral portion contacts the guide surface of the annular element and is thereby arcuately deformed which avoids acute bending and consequent breaking of the peripheral portion.

摘要： The pressure compensator and accumulator comprises a casing having ports at opposite ends. A hermetically sealed air chamber means of elastomeric material is loosely housed within the casing. The device is serially inserted in the flow line by connecting one port to an open end of the flow line, and connecting the adjacent open end of the flow line to the opposite port, whereby flow takes place through the casing from one port through the opposite port. Means are provided to prevent the blocking of the outlet port by the air chamber means when the means moves toward the outlet port under the influence of the flow.
