US 2025/0155034 A1 · Stacked Valve Assembly

Abstract

An apparatus and method of stacked valves that selectively move the stacked valves into various switched positions using a single actuator. A first valve of the valve stack is movable into one or more switched positions by an actuator that drives the first valve in a first or a second direction for a first or a second distance. Second and third valves of the valve stack are selectively movable into one or more switched positions by motion transfer stages. The motion transfer stages selectively transfer the first or second direction and the first or second distance movements of the first valve to the second and third valves that place the second and third valves into one of the switched positions.

Dependent claims

An apparatus comprising:

a first valve having at least one input port and at least one output port the first valve movable into at least one of a plurality of switched positions;
a drive section coupled to the first valve arranged to move the first valve into at least one of the plurality of switched positions;
a second valve having at least one input port and at least one output port the second valve movable into at least one of a plurality of switched positions;
a first tab coupled to the first valve;
and
a second tab coupled to the second valve,
wherein the moving of the first valve by the drive section engages the first tab with the second tab causing the movement of the second valve into one of the plurality of switched positions.
