| 141 | High-pressure fuel pump | US13045669 | 2011-03-11 | US08720316B2 | 2014-05-13 | Hans-Peter Deeg |
| A high-pressure fuel pump includes a housing and a swash plate which is mounted in the housing and is arranged in an oil space of the housing. A drive shaft is connected to the swash plate and passes through a housing opening, and with a seal for the drive shaft, which seal is mounted in the housing in the region of the housing opening. The high-pressure fuel pump has a plurality of pump elements for sucking up, compressing and ejecting fuel, which pump elements can be acted upon consecutively by the rotatable swash plate. In a pump of this type, the fuel pump has at least one magnet, the magnetic force field of which acts on the oil space of the housing. Premature wear of the pump, in particular premature wear of the seal, is avoided since the magnet separates off iron-containing dirt particles found in the oil. | ||||||

| An electric pump for supplying a hydrogen gas to a fuel cell includes a rotary shaft rotatably inserted through an electric motor, a transmitting member provided on one of an outer peripheral surface of the rotary shaft and an inner peripheral surface of the electric motor so as to be rotatable therewith, and a groove formed in the other of the outer peripheral surface of the rotary shaft and the inner peripheral surface of the electric motor for the transmitting member to be inserted therein. The groove transmits a rotary torque of the electric motor to the rotary shaft by contacting an inner surface of the groove and the transmitting member and has an opening width along a rotary direction of the rotary shaft which is larger than the width of the transmitting member. The groove and the transmitting member produce an impact torque when the electric pump is started. | ||||||
| 144 | Vane pump consisting of a two-part stator | US11575531 | 2005-09-16 | US08403656B2 | 2013-03-26 | Ulrich Fromm |

| 145 | FRETTING-CORROSION-PREVENTION OSCILLATING VANE TYPE PUMP ACTUATOR | US13512545 | 2011-04-14 | US20120237384A1 | 2012-09-20 | 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. | ||||||

| 151 | Power steering pump relief system filter | US11504165 | 2006-08-15 | US07556479B2 | 2009-07-07 | William Joseph Foor |
| Accordingly, the present invention provides a power steering pump having a filter that removes contaminants from fluid flowing through the relief system of the power steering pump. The power steering pump includes a housing having a longitudinal bore communicating with a fluid outlet. A fluid discharge port communicates with the bore and a fluid bypass port also communicates with the bore. A flow control member is situated in the bore and forms a outlet passage communicating with the fluid outlet. A flow control valve is slidably received in the bore. The flow control valve operates to open and allow communication between the fluid discharge port and the outlet passage in the flow control member. When the fluid flow from the fluid discharge port reaches a suitable pressure, the valve opens further to allow fluid flow from the fluid discharge port to the bypass port. A fluid pressure passage communicates pressure from the fluid outlet to a pressure sensing chamber forming part of the flow control valve assembly. A filter located downstream from the flow control member operates to filter fluid passing through the fluid pressure passage, and thereby, prevents contamination from entering the relief system of the power steering pump. | ||||||
