Embodiment Construction

[0018] Methods and apparatus for cooling a solenoid coil during operation of a fluid transfer assembly are described herein. In some embodiments, an apparatus includes a pump assembly and a pumping element. The pump assembly defines a first pumping chamber and a second pumping chamber, wherein the second pumping chamber is fluidly isolated from the first pumping chamber. The first pumping chamber is fluidly coupled to the first fluid path, and the second fluid chamber is fluidly coupled to the second fluid path. The apparatus also includes a pumping element configured to move within the pump assembly between a first configuration and a second configuration. The pumping element moves the first fluid into the first pumping chamber and the second fluid into the second pumping chamber when the pumping element moves from the first configuration to the second configuration. When the pumping element is moved from the second configuration to the first configuration, the pumping elem...

Abstract

In some embodiments, an electromagnetic actuation pump comprises a first pumping chamber and a second pumping chamber, wherein the first pumping chamber delivers fluid from the pump to some portion of the vehicle to facilitate the operation of the vehicle. The second (or "parasitic") pumping chamber implements a forced convection cooling method that utilizes parasitic pumping losses to generate flow within and / or around the solenoid coil to cool the coil and / or maintain the temperature of the coil during operation. In this manner, the second pumping chamber produces a thermally related increase in the flow that reduces the resistance of the solenoid coil of the electromagnetic actuator pump.
