ABSTRACT:
The stem of an inching valve for a power-shift transmission, particularly for lift trucks, is controlled by a hydraulically-operated piston whose axis is distinct from and parallel to the axis of the stem and which is connected to the stem by means of a mechanical transmission. The risk of contamination of the fluid used for operating the piston (which is the fluid of the vehicle's braking circuit) by the oil used in the power-shift transmission is thus avoided.
