摘要： 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.

摘要： An exemplary pump-head includes a pump housing having first and second housing portions forming a pump-cavity and a magnet-cavity. The pump-cavity contains a movable pumping element, and the magnet-cavity contains a driven magnet coupled to the movable pumping element. The magnet is driven by a moving external magnetic field, which correspondingly moves the pumping element in the pump-cavity in a pumping manner. The second housing portion has inlet and outlet ports and defines at least respective portions of the magnet-cavity and pump-cavity. The first housing portion is detachable from the second housing portion to allow the pumping element to be accessed and carried away with the first housing portion, without disturbing the second housing portion.

摘要： A shaft sealing device comprising: a first member; a second member provided with a through-hole through which the first member passes; a sealing member configured to seal a gap between the through-hole and the first member; a rotation restricting part restricting relative rotation between the first and second members; and an axial displacement restricting part restricting the axial displacement of the sealing member. The rotation restricting part includes a first contact portion provided on the first member, a second contact portion provided on the sealing member and an inclined surface included on the first contact portion. The axial displacement restricting part includes a stopper surface. When the sealing member rotates in one direction relative to the second member by being dragged by the first member, the sealing member contacts the stopper surface to restrict the axial displacement of the sealing member.

摘要： The present invention provides a servo actuated operating mechanism for a coacting lobed rotor positive displacement supercharger combining a low cost and capacity electromagnetic clutch with a small oil pump internal to the supercharger unit. The oil pump supplies on demand oil pressure from oil in a hydraulic clutch housing or the supercharger timing gear case and acts as a servomechanism to actuate an internal hydraulic clutch. The hydraulic clutch can be engaged over a much wider range of speeds and loads than is possible with an electromagnetic clutch alone. The electro-hydraulic servomechanism provides improved highway fuel economy relative to an electromagnetic clutch as the engagement speed could be moved to a higher rotational speed (rpm). The internal hydraulic system makes higher supercharger engagement speeds possible with a hydraulic system, but without the assembly and leak issues associated with externally plumbed engine oil system actuated clutches.
摘要翻译：本发明提供一种用于将低成本和高容量的电磁离合器与增压器单元内部的小型油泵结合的共同作用的叶片转子正排量增压器的伺服致动操作机构。油泵在液压离合器壳体或增压器正时齿轮箱中提供油的按需油压，并且用作致动内部液压离合器的伺服机构。液压离合器可以在比单独的电磁离合器可能的更宽的速度和负载范围内接合。电液伺服机构提供了相对于电磁离合器提高的公路燃料经济性，因为接合速度可以移动到更高的转速（rpm）。内部液压系统通过液压系统可以实现更高的增压器接合速度，但是没有与外部发动机油系统驱动离合器相关的组件和泄漏问题。

摘要： An oil pump in which pulsation vibration due to the dynamic pressure on the discharge port side can be attenuated. In an oil pump for transporting fluid from a suction port to a discharge port by the rotation of a rotor mounted in a pump casing, a resonator configured from an introduction path and a chamber is formed with respect to a discharge flow channel that communicates with the discharge port in the flow direction of the discharge flow channel. A channel in a direction different to the flow direction of the discharge flow channel is communicatingly formed in the vicinity of the resonator.
