    Abstract: IN PREFERRED FORM, A CONTROLLER FOR A VEHICLE LEVELING SYSTEM THAT HAS AN AUXILIARY LOAD-SUPPORTING AIR SPRING FOR MAINTAINING A VEHICLE HEIGHT. AN ELECTRICAL SWITCH IS MOUNTED ON THE AIR SPRING AND IS RESPONSIVE TO THE HEIGHT OF THE VEHICLE CHASSIS TO SELECTIVELY CONTROL EITHER ENERGIZATION OF AN ELECTRIC MOTOR DRIVEN COMPRESSOR TO EXHAUST OR PUMP-DOWN THE AIR SPRINGS OR ENERGIZATION OF A SOLENOID CONTROLLED VALVE TO COMMUNICATE A STORAGE TAND WITH THE AIR SPRING DURING PUMP-UP OR INFLATION PHASE OF OPERATION. THE SWITCH INCLUDES A PRESSURE SENSING CHAMBER IN COMMUNICATION WITH THE AIR SPRING AND A PRESSURE RESPONSIVE PISTON OPERATED BY PRESSURE IN THE AIR SPRING TO CONDITION THE SWITCH TO SHUT-OFF THE COMPRESSOR.

    Abstract: In preferred form, a fluid controller having a body that supports a reciprocating shaft for actuating an elongated operating stem of a valve assembly. The valve assembly includes a valving element fixedly secured to the stem which is maintained in biased sealed relationship with a valve seat by spring means when the valve is closed. The reciprocating shaft has means thereon engageable with the stem to angularly tilt the stem to open the valve in response to the angular relationship between the operating shaft and the stem and independently of the distance between lineally spaced points on the stem and the valve seat of the assembly.
