A fluid pump valve assembly includes: a valve body; a fluid inlet and a fluid outlet defined in the valve body; an inlet disk and an outlet disk movably disposed in the valve body; and a valve seat fixed within the valve body and including a disk member including at least one first aperture defined axially through the disk member, and at least one second aperture defined axially through the disk member, the inlet disk and the valve seat forming at least part of an inlet valve and the outlet disk and the valve seat forming at least part of an outlet valve. An inlet chamber is disposed upstream of the inlet valve, a pump chamber is disposed between and in fluid communication with the inlet valve and the outlet valve, and an outlet chamber is disposed downstream of the outlet valve. The inlet chamber surrounds the outlet chamber.

Pump valve configuration and assembly method

A valve assembly for a fluid pump includes a valve body; a fluid inlet and a fluid outlet defined in the valve body; a valve seat; and an inlet disk disposed in the valve body having an inner portion, an outer portion fixed within the valve body, and a plurality of legs connected between the inner portion and the outer portion so that the inner portion is movable between a first position against the valve seat and a second position spaced apart from the valve seat. The connection between the legs, the inner portion and the outer portion provides a spring bias force to the inner portion against movement of the inner portion from the first position. The plurality of legs, the inner portion and the outer portion are configured such that the spring bias force is asymmetric as applied to the inner portion of the inlet disk.

In some embodiments, a solenoid-actuated pump includes a first pumping chamber and a second pumping chamber, where the first pumping chamber delivers fluid from the pump to portions of a vehicle to facilitate the operation of the vehicle. The second (or 'parasitic') pumping chamber implements a forced convection cooling method, which utilizes parasitic pumping loss to produce a 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 flow that reduces thermally-related increases in electrical resistance of the solenoid coil of the solenoid-actuated pump.

Methods and apparatus for cooling a solenoid coil of a solenoid pump

In some embodiments, an apparatus includes a solenoid and a solenoid controller. The solenoid is configured to move an actuator a distance between a first position and a second position when a voltage is supplied to the solenoid. The solenoid controller is implemented in at least one of a memory or a processor, and includes a feedback module and an output module. The feedback module is configured to receive a feedback signal associated with a solenoid current after the voltage is removed from the solenoid. The feedback module is further configured to determine whether the distance is less than a maximum distance between the first position and the second position (i.e., a 'stroke'). The output module configured to produce an output signal when the feedback module determines that the distance is less than the maximum distance.

A new Tether Ball Safety Cover for offering a tether ball cover to prevent injury caused by contact with the tether ball eye loop or rope retaining knot. The inventive device includes a tether ball, a conical shaped protector, inner Velcro strips, and outer Velcro strips. In use, referring to FIGS. 5 and 6, the conical shaped protector 14 is slid onto the rope 16. Then the rope 16 is threaded through the tether ball eye loop 40 and the rope retaining knot 18 is tied into the end of the rope 16 to prevent the rope 16 from slipping back through the tether ball eye loop 40. Lastly, the conical shaped protector 14 is slid down to engage the tether ball 12, mating inner Velcro strips 28 with outer Velcro strips 26, thereby removably holding the assembly together and therefore providing a shield to prevent injury causing contact with the tether ball eye loop 40 or the rope retaining knot 18.

The present invention provides an externally engagable clutch which comprises an inner rotating hub member operably attached to a rotating back plate upon which is pivotly mounted an eccentric arm and a circular shaped clutch assembly provided with a clutch lining. An outer rotating clutch drum hub is provided which is rotatably attached to and in alignment with the inner rotating hub. Clutch drum hub eccentric cam means are mounted on the outer peripheral surface of the outer drum hub. Cam follower means is rotatably mounted upon the eccentric arm in constant rolling contact with a cam surface. As the cam follower means is displaced over the peripheral surface of the cam the eccentric arm is caused to shove the clutch assembly outwards into frictional contact with the clutch drum thereby connecting the driving source with the driven member. A throw out lever assembly is rotatably mounted upon the outer portion of the outer rotating clutch drum hub for laterally displacing the cam or cam follower. A preferred embodiment is directed to displacing the cam follower rather than the cam faces.
