摘要： A clutch position selector valve for use with a transmission for an industrial vehicle. The selector valve selectively establishes communication between a fluid pressure source and a forward clutch chamber or a reverse clutch chamber. The selector valve comprises a valve body having an inlet port communicating with the pressure fluid source, a forward clutch port communicating with the forward clutch chamber, a reverse clutch port communicating with the reverse clutch port and a drain port communicating with a fluid reservoir, and a valve element selectively establishing communication between the inlet port and the forward or reverse clutch ports. The valve element is removably and reversibly disposed within the interior of the valve body and cooperates with a selector lever to shift the element between the forward and reverse positions. This reversible feature permits the operating lever to be located on either side of a steering column for convenience of operation.
