Abstract
Official abstract text for this publication.
A valve assembly for a pump driven by a motor is provided. The motor has an output shaft for driving the pump. The valve assembly includes a valve element concentrically attached to the output shaft of the motor. The valve assembly includes a gear set mounted on the output shaft of the motor. The gear set provides a motive force to the valve element through the output shaft for axially translating between an open position and a closed position on the output shaft. A spring located between the gear set and the valve element biases the valve element against the motive force provided by the gear set.
First claim
Opening claim text (preview).
What is claimed is: 1 . A valve assembly for a pump driven by a motor, the motor having an output shall to drive the pump, the valve assembly comprising: a valve element concentrically attached to the output shaft of the motor; a gear set mounted on the output shaft of the motor, wherein the gear set provides a motive force to the valve element, through the output shaft, to axially translate between an open position and a closed position on the output shaft; and a spring disposed between the gear set and the valve element, wherein the spring biases the valve element against the motive force provided by the gear set. 2 . The valve assembly of claim 1 , wherein the gear set is a helical gear set or a worm gear set. 3 . The valve assembly of claim 1 further includes a bearing element adapted to restrict the valve element to axially translate past the closed position and the open position.
