Abstract: A governor control linkage having a first manually operated actuator and a second manually operated actuator provides for setting of an engine governor control arm at a particular operating position by means of the first manually operated actuator, a coupling and an extensible link interconnected with the governor control arm. The coupling operatively locks the first manually operated actuator relative the setting of the governor control arm while allowing the second actuator to temporarily reposition the governor control arm at an intermediate setting. The extensible link in the first manually operated actuator returns the governor control arm and the second manually controlled actuator to the prepositioned setting upon release of the second actuator.

Abstract: A drive train includes a hydrostatic transmission unit and a multiple speed range transmission unit arranged in series between a prime mover and a primary output shaft, variable displacement and torque transmitting capacity of the hydrostatic transmission unit being adjusted by hydraulic controls including a speed control valve for developing a differential pressure signal proportional to a desired rate of operation, a modulating valve for regulating the differential pressure signal corresponding to accelerating and decelerating operation of the transmission, a directional control valve for determining the direction of operation of the hydrostatic transmission unit, and a range selector valve for shifting the operating speed range of the multiple speed range transmission as the hydrostatic transmission approaches a limit of displacement, the displacement of the hydrostatic transmission being automatically reset in response to shifting of the multiple speed range transmission.

Abstract: An ultra-narrow aisle lift truck vehicle has a body including discrete front and rear portions connected by a pair of elongated stabilizing and support members. The stabilizing and support members are movable vertically in tracks on the body portions so that they provide both structural support and integrity between the front and rear portions as well as being selectively movable into and out of a ground engaging position to perform a stabilizing function. A pair of vertical masts mounted on the front and rear portions support a vertically movable carriage assembly. The carriage assembly includes a carriage having a pair of horizontally directed forks thereon which may extend into laterally adjacent opposite sides of the vehicle and return to a position within the body and between the lateral sides thereof. The carriage is mounted on an extension pantograph and is turnable about a vertical axis by means of a motor to accommodate such lateral positioning.

Abstract: A hydraulically limited fuel injection nozzle includes a lift control washer disposed about an elongated check valve stem so that the washer cooperates with a surrounding sleeve when acted upon by a pressure difference caused by fluid flow to control lift of the check valve. The arrangement moves the main flow restriction upstream of check valve.
