| 97 | Overheat protection for fluid pump | US10286083 | 2002-11-01 | US06837688B2 | 2005-01-04 | Robert R. Kimberlin; Robert E. Harvey, III; Jie Jiang |
| An apparatus for detecting the presence of an overheat condition in a fluid pump includes a pump head for receiving a fluid at a first pressure and outputting the fluid at a second pressure that is greater than the first pressure. A motor is positioned adjacent the pump head to drive the pump head to pressurize the fluid. A single overheat sensor senses an overheat condition in the pump head and an overheat condition in the motor. When a threshold temperature is sensed by the overheat sensor, a switch is activated to prevent operation of the motor. In one embodiment, the overheat sensor and switch are integral and may, for example, take the form of a bi-metal switch formed in the stator windings of the motor. In alternate embodiments, the overheat sensor and switch are separate. | ||||||
| 98 | Ball check air vent for transmission pump | US10310787 | 2002-12-06 | US06817843B2 | 2004-11-16 | Maurice Leising; Charles Redinger |
| A pressure-relieving valve is connected to relieve air pressure from an internal diameter of a transmission pump. On startup, pressurized oil is delivered to the torque converter. At engine idle speed, the centrifugal effects on the oil cause any air (which may have leaked into the torque converter during the shut-down time) to accumulate at the center of the converter. Air pressure output from a torque converter escapes between the housing and the transmission pump to which it is connected. The escaped air reaches the internal diameter of the pump and it is prevented from blowing across the face of the pump to the suction side of the pump by a ball and check valve arrangement which delivers the air to a non-fluid internal part of a transmission, thereby avoiding the leakage of this air to the suction side of the pump and the possible loss of pump prime. | ||||||
| 99 | Fluid circulation path for motor pump | US10290705 | 2002-11-08 | US20030161743A1 | 2003-08-28 | Robert R. Kimberlin; Robert E. Harvey, III; William M. Larson; William C. Rawnsley, JR. |
| A fluid pump includes a pump head having an inlet for receiving fluid at a first pressure and an outlet for outputting fluid at a second pressure greater than the first pressure. Pressurized fluid is directed through a first passage to the outlet without the pressurized fluid leaving the pump head prior to reaching the outlet. A second passage directs pressurized fluid to a fluid circulation path which is at least partially external to the pump head with the fluid circulation path terminating adjacent the outlet. Pressurized fluid passing through the first and second passages is directed to the outlet without being re-pressurized by the pump head. The first and second passages are in opposed relation to one another to provide balancing of thrust produced by the flow of pressurized fluid through the passages. An electric motor drives the pump head. The fluid circulation path may include portions of the electric motor. | ||||||
| 100 | Control for progressive cavity pump | US09813583 | 2001-03-21 | US06530750B2 | 2003-03-11 | Ernest Bennett Mills |
| A progressive cavity pumping system includes a pump housing, a rotor member operatively received in the pump housing, a prime mover coupled to the rotor member for driving the rotor member in first and second directions and a controlling means for actuating the prime mover, wherein the controlling automatically causes the rotor member to be driven in the second direction after shut down or idling of the pumping system. A method of operating the pumping system includes automatically driving the rotor member in a second direction after initiating shut down or idling of the pumping system and prior to start up of the same. | ||||||
