Abstract:
1. A valve for regulating fluid flow comprising: a stepper motor; a first valve portion that includes an inlet port for receiving fluid into the valve; a second valve portion that includes an outlet port for dispensing fluid from the valve; a third valve portion located between the first valve portion and the second valve portion; a first member that is rotatable and operatively attached to the stepper motor; a second member, having a first portion and a second portion, which is engageable with the first member for linear movement of the second member between a first position and a second position when the first member is rotated by the stepper motor, wherein the first member and the second member are located within the third valve portion and the second member having a flow path therethrough for directing fluid flow in a direction parallel to the direction of the linear movement of the second member and the first portion of the second member located in the first position can block fluid flow between the first valve portion and the third valve portion through the flow path and the second portion of the second member located in the second position can allow fluid flow between the first valve portion and the third valve through the flow path; and a biasing mechanism that is in contact with the second member and operable to move the second member to the second position in the event the stopper motor is not powered.
