    Abstract: A variable capacity pump/motor (100) has a meshing internal and external gear set (128, 124) disposed between an upper mandrel (140) and a lower mandrel (110), each including a flange (120, 144) extending towards the gears to divide a pump/motor chamber into suction and discharge chambers. The outer gear (126) is fixed and the internal gear (128) is axially moveable with respect thereto. The inner gear (128) and the upper mandrel (140) move in response to changing pressures in the casing (102), allowing the motor to vary displacement and the pump to vary its output based on supplied fluid pressure or based on the speed of the prime mover (20). An external configuration (200) includes a pair of meshing gears (214, 218) mounted on separate shafts (222, 224) in a casing (202). One gear (214) is fixed and the other (218) is axially moveable with respect thereto and moves in response to changing pressures in the casing. Each of the gears is sealed by a seal/bushing (226, 228) on a free end thereof.

    Abstract: A telescoping gear pump comprises a bolt, a Bellville washer, a wear plate, a seal housing, a seal spring, a spur gear including a wear lobe, a seal ring and a case drain path, a shaft, a ring gear including a wear lobe, seal ring, and a case drain path, seal, a bolt assembly including a Bellville washer and bolt, and a pressure plate. The assembly provides pressure to a fluid to maintain a seal within a telescoping pump/motor during operation. The wear lobe reduces wear while maintaining fluid pressure.

    Abstract: A low noise gear set 300 for use generally and preferably with a power plant 11 having an engine 12 driving a pump 16 connected to a low pressure fluid source 18, generating high pressure fluid at an output 107, 252, 254. The idle gear 312 meshes with the drive gear 310 along two points 314, 316 of the profile 318, 320 of the corresponding gears 310, 312. The first point 314 being the root 326 of one gear tooth meshing with the tip 328 of the opposite gear tooth creating an initial first contact point 314 and a subsequent second point 316 along the profile 318, 320 when the teeth are disengaging at the first point 314 and engaging at the second point 316, forming a sealed area 322, allowing the fluid 324 to hydrostatically escape between the points 314, 316.

    Abstract: An accumulator assembly (10) comprises an accumulator cylinder (12) formed of a cylindrical, gas-impermeable shell (18) and a cylindrical gas-impermeable sleeve (20) disposed within and substantially concentric with the shell (18), An interstitial space (30) is formed between the sleeve (20) and the shell (18). A piston (22) slidably is disposed within the sleeve (20), the piston (22) separating an interior of the sleeve (20) into a first chamber (29) configured to contain a compressed gas, and a second chamber (31) configured to contain a pressurized fluid. A pair of removable axial closures (14, 16) retained to the gas-impermeable sleeve (20) at opposing ends and sealingly engaged with corresponding opposing ends of the gas-impermeable shell (18) is configured to provide maximum resistance to the tensional stress of the sleeve (20).
