    Abstract: In preferred form, a combined fluid spring component and height controller for use in an automatic leveling system for a vehicle. The controller includes a cam operator extending through a side port in the controller housing to engage a part of the spring component to reflect changes in the vehicle attitude. Intake and exhaust valve assemblies are fluidly communicated with the control chamber of the fluid spring through the valve operator port. These valve assemblies are selectively opened and closed by a reciprocating shaft connected to the cam operator by overtravel means and further connected to a damping unit that controls movement of the shaft.

    Abstract: IN PREFERRED FORM, A COMBINATION VALVE AND ELECTRIC SWITCH ASSEMBLY ON AN AIR TANK ENCLOSING A COMPRESSOR. THE INTERIOR OF THE TANK IS CONNECTED TO AN OUTLET IN THE ASSEMBLY. THE ASSEMBLY INCLUDES A NORMALLY CLOSED CHECK VALVE THAT IS CONNECTED BY THE ASSEMBLY TO THE COMPRESSOR INLET. A PRESSURE RESPONSIVE SWITCH IN COMMUNICATION WITH THE CHECK VALVE COMPLETES AN ENERGIZATION CIRCUIT FOR ELECTRIC COMPRESSOR DRIVE MOTOR WHEN THE INLET IS SUPERCHARGED AND OPENS THE CHECK VALVE SO THE COMPRESSOR WILL CHARGE THE TANK. THE SWITCH INCLUDES AN OVERTRAVEL MECHANISM AND SPRING DETENT ARRANGEMENT FOR PRODUCING SNAP OPENING AND CLOSURE OF THE ELECTRICAL SWITCH OF THE ASSEMBLY IN RESPONSE TO CHANGES IN SENSED PRESSURE.
