    Abstract: A pump for applying fluid to an assembly, the pump including: a pump housing featuring a circumferential wall surrounding a delivery chamber of the pump, an end-facing housing wall including an outer end-facing surface of the housing which faces axially away from the delivery chamber, an inlet and an outlet for the fluid which emerges on the outer end-facing surface of the housing; a delivery member, moveable within the delivery chamber, for delivering the fluid from a low-pressure side of the pump which includes the inlet to a high-pressure side of the pump which includes the outlet; and an axial gasket which fully surrounds the outlet, in order to separate it from the low-pressure side, in an axial view onto the end-facing wall of the housing. The axial gasket is a spring gasket in the form of a disc spring or hollow-profile spring or V-profile spring or bellows spring.

    Abstract: A supercharger rotor with reduced rotational inertia may result in increased performance of a supercharger. The rotor may include composite material and may be extrusion molded, injection molded, or otherwise molded or laid-up. In certain embodiments, the rotor may include a core with a central portion and one or more radially extending portions. The core may be extruded or formed of stacked sheets. A molded portion of the rotor, including one or more lobes, may be molded over a corresponding one of the radially extending portions. In other embodiments, a main portion of the rotor includes one or more lobes but no central hole nor a corresponding shaft extending between ends of the main portion. Instead, stub shafts are attached to the ends of the main portion. The increased performance may include decreased noise, decreased cost, increased reliability and/or durability, increased thermal efficiency, an increased power-to-weight ratio, etc.

    Abstract: This invention relates to a Dry Running Flexible Impeller Pump and Method of Manufacture designed to provide a flexible impeller pump capable of being run dry for extended periods of time without damage. The pump's components are comprised of low friction materials limiting the heat of friction created by the impeller in use. The impeller is cast of pre-molding silicone substrate containing a quantity of mold release that will not prevent the deposition of a low friction compound coating on the surface of the impeller in a mold that is treated with a low friction industrial coating. Once the impeller is removed from the mold it is solvent cleaned, vacuum baked at a temperature high enough to drive off residual traces of mold release or compounds used to maintain the silicone substrate in suspension, and then coated with a polymer of Poly Para Xylylene by vacuum deposition.

    Abstract: Engineered surface treatments are applied to different types of hydraulic motors and pumps to improve the life of the contacting surfaces (17, 18) in said motors and pumps. The engineered surface treatments are selected from texture modifications and tribiological coatings and selectively applied to one or both of the contacting surfaces to reduce friction and improve fatigue life under poor lubrication operating conditions.

    Abstract: A hybrid elastomer/metal on metal motor for a helical gear device includes a rotor and stator comprising a hydraulic motor that produces work when a working fluid is pumped therethrough. The improvement consists of the stator being, for part of its length, a conventional or even wall stator, using an elastomer to form a seal against the moving rotor. The stator's remaining length comprises a profiled rigid surface that forms a seal directly with the moving rotor. This gives the motor the high efficiency of the elastomer sealing against the rotor, and simultaneously provides a backup of the stator's rigid portion allowing continued motor operation at reduced efficiency, if the elastomer part failed in service. The application also discloses combinations of a regular disk stack with a rubber lining, a rigid material disk stack and a circular rigid sleeve which react to rotor sideloading while permitting proper rotor orbiting.

    Abstract translation: 用于螺旋齿轮装置的用于金属电动机的混合弹性体/金属包括转子和定子，所述转子和定子包括当泵送工作流体时产生作业的液压马达。 改进之处在于，定子的一部分长度为常规或均匀的壁定子，使用弹性体来形成对移动转子的密封。 定子的剩余长度包括直接与移动转子形成密封件的成型刚性表面。 这为电机提供了高效率的弹性体密封抵抗转子，并且同时提供了定子刚性部分的支撑，如果弹性体部件在使用中失效，则能够以更低的效率继续电机运行。 本申请还公开了一种规则的磁盘堆叠与橡胶衬套，刚性材料盘堆叠和圆形刚性套管的组合，其在允许适当的转子轨道运动的同时对转子侧面加载作出反应。
