The thrust bearing unit includes a thrust runner mounted to the shaft that rotates against a thrust bearing base fixed in the housing. An annular, metal thrust runner wave spring has an inner diameter surface in contact with the shaft and an outer diameter surface in contact with the runner bore. The wave spring has a transverse width between the inner diameter surface and the outer diameter surface that is elastically deflectable, exerting an inward bias force against the shaft and an outward bias force against the runner bore. | ||||||

| 108 | Fretting-corrosion-prevention oscillating vane type pump actuator | US13512545 | 2011-04-14 | US08899948B2 | 2014-12-02 | Seung-Ho Shin; Key-Yong Hong; Tomiji Watabe |
| Disclosed herein is an oscillating vane type pump actuator. The pump actuator of the present invention provides a method of preventing fretting corrosion from being caused on joined surfaces of elements. A cylinder (3c) has a comparatively low radial strength, and each of side covers (1c) and (2c) has a high radial strength. A cylindrical portion (1c-c), (2c-c) is provided on each side cover. Thus, when high pressure of work oil distorts the cylinder into a shape in which the cross-section of the cylinder becomes an ellipse-like shape, the cylindrical portions of the side covers act such that they are distorted in the same shape as that of the cylinder. Further, a passage that always communicates with a low-pressure side working chamber is formed in the contact surfaces between a fixed vane that is fixed to the cylinder and the side covers. | ||||||

| A corrugated building component and system includes a corrugated panel made up of fluted layers of sheet material. The flutes form open passages to receive connecting rods which may extend from one panel and into an adjacent panel, locking the panels together. The panels also include rabbeted edges that interfit, along with the connecting rods to produce a structural unit. A base plate or footing is described within the system with upright tie rods used to secure the assembled panels to the footing or base plate. Top, bottom, and end plates may be provided on sides and ends of elongated panels, to be joined with connecting members and reinforcing connectors. | ||||||
| 111 | Rotary fluid pressure device and improved shuttle arrangement therefor | US73838 | 1993-06-09 | US5328343A | 1994-07-12 | Marvin Bernstrom; Marvin Flaschenriem; Oliver Johnson; Sohan Uppal |
| A gerotor motor (11) of the valve-in in-star type is provided wherein a stationary valve member (17) is disposed immediately adjacent the gerotor gear set (19). The stationary valve member defines a shuttle bore (81) and disposed therein is a shuttle member (107) which moves between two operating positions (FIGS. 6 and 7) under the influence of system pressure. The shuttle valve member (107) communicates system pressure from whichever of the ports (39 or 41) is at high pressure to a pressure balancing recess (63). At the same time, the shuttle valve (107) provides fluid communication between whichever of the ports is at low pressure and a low pressure passage (83) which may be in communication with a lubrication circuit (95), or may be in communication with a case drain port, to divert a small amount of fluid to a heat exchanger. The invention provides a very small shuttle valve arrangement comprising only a single part, and eliminating a substantial amount of the machining previously required in the motor endcap (15). | ||||||
| 112 | Fluid handling device useful as a pump, compressor or rotary engine | US811414 | 1985-12-20 | US4631011A | 1986-12-23 | Roger R. Whitfield |
| A fluid handling device which when suitably configured can be used as a pump, compressor or as a rotary engine. In the illustrated application, there are three primary active components. These are two identical rotating segments or pistons and a centrally disposed rotating disk that forms chambers of variable volume with the rotating segments or pistons. The disk member carries a spherical chamber open at diametrically opposed locations to receive a pair of rotating shafts which carry the rotating segments or pistons. This spherical chamber forms a seal with complementary spherical surfaces on the rotary piston members. The disk member is journalled in two sets of bearings carried by yoke members one of which is carried by each rotating shaft. | ||||||
| 113 | Reversible unidirectional flow rotary pump | US695866 | 1985-01-21 | US4588362A | 1986-05-13 | Robin E. Child |
| A gerotor pump is arranged for unidirectional flow irrespective of direction of rotation of the pump by arranging for displacement of the axis of eccentricity of the annulus and rotor upon drive reversal, the annulus being mounted in a carrier 14, FIG. 1, with freedom for movement in a first direction within the carrier, while the carrier itself is pivoted (24) in an outer housing 15, the carrier being free for movement in a second direction within the housing. The effect of normal drive of the rotor is to hold the parts in the FIG. 1 position while pumping continues, but in the event of drive reversal a pressure fluctuation causes the annulus to be displaced within the carrier and then the carrier to be displaced within the housing so as to bring the parts to substantially the mirror image of the FIG. 1 position allowing continued pumping in the same direction from inlet to outlet under reversed drive. | ||||||
