摘要： An eccentric compensating torsional drive system for reducing the rotational eccentric conflict as between multiple eccentric rotational movement limits on the eccentric offset within the drive system, the system includes a motor, a first offset distance coupling, an offset floating bearing, a dynamic element that is driven in a first offset distance rotation by the motor, coupling, and offset floating bearing. Wherein the dynamic element is pivotally connected to a static element via a pivotal offset bearing assembly having a substantially matching offset to the first offset distance. Operationally, the offset bearing can have relative rotational movement to the coupling and dynamic element to lessen the dynamic conflict as between the first offset distance and the pivotal offset bearing assembly as the offset bearing acts as a floating variance in rotational offset via changing a radial position to the coupling and dynamic element.

摘要： A compressor may include a shell, a compression mechanism, a bearing housing, a shroud, a stator, and a rotor. The compression mechanism includes a scroll member that is attached to the shell. The shroud is rotatably fixed relative to the shell and attached to the bearing housing. The stator is fixed relative to the shell. The shroud may have an annular body including an inner surface defining a center shroud passage. The stator may have an outer surface defining a stator passage. An outer surface of the rotor and an inner surface of the stator may be spaced apart and define a discharge gap in fluid communication with the center shroud passage and the stator passage. A continuous passage may extend between a top surface of the scroll member and a bottom surface of the shroud and may be in fluid communication with the shroud passage.

摘要： A scroll pump includes a frame, a stationary plate scroll, an orbiting plate scroll, a non-energized type of tip seal or seals, an eccentric drive mechanism assembled to and supported by the frame and to which the orbiting plate scroll is assembled so as to be drivable by the eccentric drive mechanism in an orbit about a longitudinal axis of the pump, and an axial compliance system including a flexure. The flexure is interposed between a bearing of the eccentric drive mechanism and a flexure-locating surface of the eccentric drive mechanism. The flexure allows the orbiting plate scroll to move away from the stationary plate scroll in the case of an assembly process which would otherwise result in the tip seal(s) being too forcefully engaged with the plate of the opposing plate scroll.

摘要： A compressor is provided that may include a passage separator provided between an electric motor drive and a compression device to separate a refrigerant passage from an oil passage. The passage separator may include a first partition wall and a second partition wall. The first partition wall may be disposed between an inner circumferential surface of a casing and a discharge hole of the compression device, and the second partition wall may be disposed between the discharge hole and a balance weight. Accordingly, the refrigerant passage may be separated from the oil passage between the compression device and electric motor drive, thereby efficiently recovering oil to an oil storage space.

摘要： The present invention provides a scroll pump comprising: a scroll mechanism having an orbiting scroll and a fixed scroll; a drive shaft having a concentric shaft portion and an eccentric shaft portion connected to the orbiting scroll. The shaft is arranged to be driven by a motor so that rotation of the shaft imparts an orbiting motion to the orbiting scroll relative to the fixed scroll for pumping fluid along a flow path from an inlet to an outlet of the scroll mechanism. An axial lip seal is located between the orbiting scroll and the fixed scroll for resisting leakage of fluid from outside the scroll mechanism into the flow path.
