| A compressor may include first and second compression members, first and second bearing assemblies, a sensor, and processing circuitry. The second compression member cooperates with the first compression member to define a compression pocket. The first and second bearing assemblies rotatably support the first and second compression members, respectively. The first bearing assembly may include a bearing rotor and a bearing stator. The bearing stator may surround the bearing rotor and may include poles each having a winding. The sensor may measure a radial position of the bearing rotor relative to the bearing stator. The processing circuitry may be in communication with the sensor and may control electrical current supplied to the windings based on the radial position measured by the sensor to adjust the radial position of the bearing rotor relative to the bearing stator. | ||||||

| The present invention provides a gear pump having one or more gears with bearing shafts supported by respective pressure-loaded gear pump bearing blocks. Each pressure-loaded bearing block has: a bore adapted to receive the bearing shaft of a gear of the pump; a thrust face at one end adapted to slidingly engage with a side surface of the gear, and an opposing rear face at the other end, the pump being adapted such that, in use, pressurised fluid is supplied to the rear face to provide a hydraulic load urging the thrust face of the bearing block towards the side surface of the gear; and a seal carried by the rear face, the seal, in use, partitioning higher fluid pressure and lower fluid pressure portions of the rear face. The gear pump further has a pressure regulating valve arranged such that, in use, the fluid pressure difference between the higher and lower fluid pressure portions of the rear face of the bearing block is adjustable by the valve to vary said hydraulic load. | ||||||

| A fluid pump (10) or motor (100) includes a pair of enmeshed tapered rotors (22,24,122,124) having intersecting axes of rotation. The first rotor (22,122) includes a small low pressure end (34,54,134,154) and a larger high pressure end (32,52,132,152) and a spiral thread (36,56,136,156) that increases in width and depth as it progresses from the high pressure end (28,128) to the low pressure end (26,126). The second rotor (24,124) enmeshes with the first rotor (22,122), and has an identical structure, except that its threads (36,56,136,156) progress in the opposite direction. Both rotors (22,24,122,124) are mounted on sliding splines (42,62,142,162) which permit them to move, to a limited extent, into and out of their respective receiving cavities. The pressure on the high side (28,128) of the pump (10) or motor (100) tends to urge the rotors (22,122,24,124) against the walls (16,20,116,120) of the receiving cavities thereby improving their sealing capabilities and the overall efficiency of the pump (10) or motor (100) as a whole. | ||||||

To provide a vane type compressor that can appropriately keep the allocation of the clearances at the front and rear ends in the axial direction of the rotor by balancing the forces applied to the front and rear sides of the drive shaft. The clearances at the front and rear ends in the axial direction of a rotor 3 are appropriately allocated by providing, in a drive shaft 2, a passage 52 communicating between a low-pressure space 26 communicating with a suction chamber 29 and a shaft end space 15 partitioned by a rear side block 13 and the end of the drive shaft 2 and balancing the forces applied to the front and rear sides of the drive shaft 2. This prevents the compression efficiency from reducing while ensuring the smooth rotation of the rotor 3. |
