| 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. | ||||||
| 8 | Compressor with oil bypass | US11413860 | 2006-04-28 | US07674099B2 | 2010-03-09 | Stephen Dunn |
| An oil lubricated compressor which includes a bypass oil line connecting respective oil paths upstream and downstream of the motor. The bypass oil path permits oil to be detoured around the motor in a tube that is external to the compressor shell and flows back into the shell near the scroll inlet. The oil bypass line returns “excess” oil directly to sump 28, rather than having it flow from sump 27 to sump 28 through an air-gap, thereby reducing both the drag on the motor and the input power. | ||||||

| Pumps are disclosed that include a pump housing and at least one movable pumping element situated in the housing. The pumping element(s) are magnetically driven by magnetically coupling an external magnet driver (e.g., a stator) to a driven magnet located in the housing. A control circuit selectively operates the stator and a heat-producing element, so as to energize the heat-producing element especially in a potential freezing condition when the pump is not being otherwise operated. Thus, the fluid in the pump is prevented from freezing, and freeze-related pump damage is avoided. The heat-producing element can be the stator itself energized differently from when the stator is used for driving the pump. | ||||||

| PROBLEM TO BE SOLVED: To improve an oil cooling system of a horizontally oriented oil-lubricated compressor. SOLUTION: The oil lubricated compressor includes a bypass oil line connecting respective oil paths upstream and downstream of a motor. The bypass oil path permits oil to be detoured around the motor in a tube that is external to a compressor shell and flow back into a shell near a scroll inlet. The oil bypass line returns "excess" oil directly to a sump 28, rather than having it flow from a sump 27 to the sump 28 through an air-gap, thereby reducing both a drag on the motor and input power.
