Abstract

See full text

A hydraulic spool valve includes a housing, a valve element disposed within the housing, a first piston coupled to the valve element, and a first biasing member. The housing includes a pair of first ports. The valve element is selectively moveable within the housing between a first closed position and a second open position allowing fluid communication between the first ports. Hydraulic pressure against the first piston causes helical translation of the piston in a first direction, and motion of the valve element in a first direction from the first position toward the second position. The first biasing member is configured to bias the first piston and the valve element toward the first position.
