The speed retarder control system includes a plurality of solenoid valves and reducing valves so arranged to receive pressure influenced hydraulic fluid and release the hydraulic fluid to a hydraulic fluid responsive vehicle retarder at a substantially lower pressure. The fluid pressure experienced by the retarder can be incrementially varied to result in varying degrees of vehicle retardation.

The framework and operator seat support structure of a cab form part of the ductwork for an environmental control system including a pair of blowers and cooling and heating coils mounted in a hollow arm rest support portion of the seat support structure.

Environmental control system and cab combination

A hydraulic fluid reservoir is provided on a vehicle for containing fluid for use in the hydraulic system of the vehicle. The hydraulic reservoir is mounted between an upright wall forming a part of the vehicle operator's station and the backside of a water-cooled internal combustion engine. Coupled to the engine on the side remote from the reservoir is a blower-type fan. The reservoir is provided with a centrally located air duct means aligned with the engine and blower fan and the reservoir is so located that the engine-driven fan draws air around and through the reservoir to provide forced convection cooling of the fluid contained in the reservoir. The air duct means are so located relative to outlet and inlet ports of the reservoir that fluid flowing from the inlet to the outlet port will be deflected or baffled by the duct means.
