An inching valve for power-shift transmissions, particularly for lift trucks.

摘要

The stem of an inching valve for a power-shift transmission, particularly for lift trucks, is controlled by a hydraulically-operated piston (16) whose axis (18) is distinct from and parallel to the axis (19) of the stem (7) and which is connected to the stem (7) by means of a mechanical transmission (21). The risk of contamination of the fluid used for operating the piston (16) (which is the fluid of the vehicle's braking circuit) by the oil used in the power-shift transmission is thus avoided.
