20090208356 - Scroll-type refrigeration compressor: Compressor has a fixed scroll and a scroll movable in an orbit relative to the fixed scroll. The fixed and movable scrolls are equipped with a spiral wrap that engage each other and delimit variable-volume compression chambers. The spiral wrap of the movable scroll has a stepped portion extending over... Agent: Oliff & Berridge, PLC

20090208357 - Rotary gear pump for use with non-lubricating fluids: An improved external rotary gear pump for use with non-lubricating fluids such as amine is disclosed. The device uses specially coated internal parts chosen to reduce friction and improve wear characteristics so that the resulting pump will operate for a minimum warranty period of one year.... Agent: Alworth Law & Engineering

20090208358 - Variable displacement gear pump: The variable displacement gear pump for a loading system in an industrial vehicle has main and sub gear pump portions, suction, discharge and bypass passages, and check and opening valves. The main gear pump portion has main drive and driven gears, and has suction and discharge side spaces. The sub... Agent: Woodcock Washburn LLP

20090202375 - Continuously variable displacement vane pump and system: A traditional continuously-variable vane pump is subject to a significant energy loss as its displacement is controlled by the output pressure f the pump rather than the changing requirements of the lubrication system A vane pump (20) is provided which has an output pressure hat can be selected from a... Agent: Magna International, Inc.

20090202376 - Scroll-type fluid machine: A scroll-type fluid machine has a movable scroll (50) that forms pressure chambers (52) in between the movable scroll (50) and a fixed scroll (40) and is orbitable relative to the fixed scroll (40), a support wall (14) that is provided for the housing (10) and supports thrust load transmitted... Agent: Cohen, Pontani, Lieberman & Pavane LLP

20090202377 - Gerotor and method of assembling the same: A gerotor and methods for assembling the gerotor are disclosed. The gerotor includes a pump housing having a channel and a rotor positioning cavity, a pump shaft, an inner rotor, and an outer rotor. The pump shaft has central pump shaft axis and the inner rotor has a central inner... Agent: Whyte Hirschboeck Dudek S C Intellectual Property Department

20090196780 - Variable displacement vane pump with dual control chambers: A traditional variable-displacement vane pump is designed to operate at an equilibrium pressure which meets the worst case scenario. Thus, at lower speeds energy will be wasted as the pump will supply working fluid at a greater pressure than is required. A variable capacity vane pump (20) is provided which... Agent: Magna International, Inc.

20090196781 - Mode changing apparatus for a scroll compressor: A mode changing apparatus for a scroll compressor is provided that may include a low-pressure passage that communicates with a suction side formed by an orbiting motion of an orbiting scroll, an intermediate-pressure passage that communicates with an intermediate-pressure side formed by the orbiting motion of the orbiting scroll, a...
