Abstract: A pneumatic circuit includes a source of fluid pressure 11, a selector valve 12, a control valve 14, and a power cylinder 15. The control valve 14 includes main valves 35 and 45 and a pilot interlock valve 27. The main valves 35 and 45 include a main inlet port 36, a main exhaust port 38, and cylinder ports 37 and 47. The pilot interlock valve 27 includes a pilot inlet port 28, an interlock port 30, and a signal port 29 which communicates with signal chambers 39 and 49. The control valve 14 is mounted on a motor vehicle transmission, and a mechanical actuator 16 moves between an extended position when the transmission is out of the neutral position and a retracted position when the transmission is in the neutral position. When the actuator 16 is in the extended position, the pilot interlock valve 27 is retained in an interlocked position to maintain the pressure condition existing in the signal chambers 39 and 49. When the actuator 16 is retracted, the pilot interlock valve 27 can move to an actuating position in which the pressure condition in the signal chambers 39 and 49 can be changed by operation of the selector valve 12 to shift the cylinder 15.

Abstract: A hydraulic control for an automatic transmission has a plurality of shift control valves for controlling the interchange of drive ratios within the transmission. The shift control valves each have a control chamber subjected to substantially constant pressure and a shift control chamber having an area proportional to the respective control chamber which is subjected to a variable control pressure. The variable control pressure is controlled at discrete levels by a single pulse width modulator (PWM) solenoid. The respective area ratios of the shift control chambers to the controlled chambers determines the distinct shift point of each shift valve.

Abstract: A diaphragm multi-port valve assembly particularly for controlling cylinder and piston assemblies. The valve assembly has communicating chambers which are normally separated by a diaphragm, the chambers being connected by a bleed so that the pressures in the two chambers can equalize. Each chamber is connected to or separated from an appropriate port or other chamber by a pilot valve.

Abstract: A sliding-spool direction control valve wherein the valve body has a central space for a center land which is rigid with the shank of the valve spool. The outer lands of the spool have axially extending recesses for the respective end portions of the shank. The center space is disposed between two seats and communicates with a pressure port flanked by two working ports which, in turn, are flanked by two return ports. The outer lands are disposed between the respective working and return ports and are connected with pistons which are movable in the valve body to thereby shift the spool so that the center land engages the one or the other seat. The movements of spool can be initiated by a single electromagnetic pilot valve or by two discrete pilot valves.

Abstract: An oppositely spring loaded spool-type valve is also pilotpressurized oppositely to control pressure liquid flow past three ball checks and through associated external lines to two hydraulic load actuating cylinders. One of these is a doubleacting cylinder selectively pressurized at its opposite ends, and the other is a single-acting, spring return cylinder pressurized at only one end, these cylinders being parts of an external system controlled by the valve. Three two-way solenoid actuated valves are operated under the control of pushbutton switch means to govern the voiding of hydraulic liquid from the respective cylinder ends in certain phases of the operation of the valve; and hydraulic operating pressure is supplied by a motor powered pump. The operation of the pump is also responsive to pushbutton switch operation, whether by itself along or conjointly with the operation of the pressure-dumping solenoid valves, in the said certain phases of operation. The pump pressurizes a valve manifold with which three ball check-governed passages are placed in communication under control of the valve spool.
