Abstract: A pressure vessel in the form of a hydro-pneumatic flexible bladder accumulator is provided which includes a shell formed of a cylindrical tube. An open-ended thimble-shaped deformable bladder of resilient material is positioned within the shell. A port plate is attached to one end of the tube, and a closure cap is retained in the other end of the tube. The cap may be retained in the other end of the tube, for example, by a removable locking ring. The closure cap has an inner end which may be displaced radially inwardly from the inner surface of the shell, and it has three axially spaced peripheral grooves on the inner end which respectively receive an O-ring to prevent leakage of liquid out of the accumulator, and two integral beads that surround the mouth of the bladder. One of the integral beads of the bladder has the shape of an O-ring, and it is received in one of the grooves to form an effective seal for the interior of the bladder. The other integral bead has a V-shape and it serves as an anchoring means for the bladder, and it is received in the other groove. An anti-extrusion button valve is provided on the other end of the bladder which eliminates the need for the prior art spring-loaded poppet valve assembly. A spacer ring of yieldable material is also provided at the other end of the shell, adjacent the port plate.

Abstract: The invention relates to a hydropneumatic accumulator in which a bladder or membrane supported within a vessel establishes a chamber for confining a compressible fluid within the vessel and also provides means for supporting a valve plate opposite inlet and outlet ports arranged so that as the valve plate position responds to pressure changes normal flow between the ports may be maintained and extruding of the bladder or diaphragm into the outlet port prevented.

Abstract: Wave-motion compensating apparatus for a crane is provided, which includes a hydro-pneumatic accumulator and an hydraulic ram, and additional components for controlling the fluid connection between the accumulator and the ram. The apparatus is intended to be coupled to a crane on an off-shore oil drilling rig, or the like, and it serves to compensate for the rising and falling wave motion between a vessel being unloaded and the crane. The compensating apparatus initially causes the load carrying cable of the crane to be maintained at a slight substantially constant tension permitting the load to rise and fall with the motion of the vessel. The apparatus at this time extracts and stores energy from the up and down motion of the load; then, after a few up and down cycles, the apparatus exerts a lifting force on the cable to lift the load clear of the crest of the next wave. The foregoing is achieved without the need for any external energy source apart from the wave motion itself. The crane then takes over and the energy stored in the compensating apparatus slowly bleeds away, and the apparatus is returned to a reset condition for the next load.

Abstract translation: 提供了一种用于起重机的波浪运动补偿装置，其包括液压气动蓄能器和液压柱塞，以及用于控制蓄能器和压头之间的流体连接的附加部件。 该装置旨在联接到离岸石油钻井平台等上的起重机，并且其用于补偿卸载的船舶与起重机之间的上升和下降波浪运动。 补偿装置最初使起重机的承载缆索保持在轻微的基本上恒定的张力，允许负载随着船舶的运动而上升和下降。 该装置此时从负载的上下运动中提取和储存能量; 然后，在几个上下循环之后，该装置在电缆上施加提升力以将负载提升离开下一波的波峰。 在不需要任何外部能量源的情况下，除了波浪运动本身之外，实现上述内容。 然后，起重机接管并且存储在补偿装置中的能量缓慢地离开，并且装置返回到下一个负载的复位条件。
