Title:
ROTARY TO LINEAR VALVE AND METHOD OF USE
Document Type and Number:
WIPO Patent Application WO2004011831
Kind Code:
B1
Abstract:
A valve is disclosed that is operable by converting rotational force of a stem (114) into linear motion of a valve closure element, such as a sleeve (102), to control flow through the valve. In a presently preferred embodiment, at least two interconnection members (110, 112) are rotatably mounted, such as with a round end, to a stem drive element (124). The interconnection members (110, 112) are slidably mounted into channel or grooves (130, 132) in a sleeve (102). Rotatable movement of the stem (114) permits rotation of the interconnection members (110, 112) whereby the interconnection members (110, 112) are constrained to slide in the channels (130, 132) whereby rotational movement of the stem (114) is converted into translational or linear movement of the valve closure element.
