Abstract: A fluid flow control apparatus has an accumulator and valve structure disposed in combination with a restricted passage to provide engagement timing for a friction device. A bypass circuit, including the valve structure on the accumulator, is provided to permit rapid filling of the friction device prior to the commencement of the accumulator stroke.

Abstract: A shift control for a four-speed automatic transmission has a hydraulic pump for supplying pressurized fluid to the control valves including a manual valve, a 1-2 shift valve and a throttle valve. The manual valve directs fluid to a low pressure regulator valve during automatic four-speed drive operation and to a governor valve during all forward drive operations. The 1-2 shift valve responds to throttle valve pressure and the higher of governor pressure or the output of the low pressure regulator valve during automatic four-speed drive operation, whereby on part-throttle acceleration, the 1-2 shift valve is upshifted by the output of the low pressure regulator valve so that a second gear start for the vehicle is provided. In full throttle acceleration, the transmission starts in first gear due to the increased throttle pressure bias to provide better vehicle performance.

Abstract: A torque converter and lock-up clutch in which a single plate fluid operated clutch is disposed between the turbine and the input shell of the torque converter. The clutch engagement chamber is formed between the turbine and the clutch plate while a clutch disengagement chamber is formed between the input shell and the clutch plate. A normally open centrifugally responsive valve is mounted on the clutch and provides a controlled flow path between the engagement and disengagement chambers in response to clutch speed thereby controlling the pressure differential between the chambers when the clutch speed is less than a predetermined value. A normally closed centrifugally responsive valve is mounted on the clutch and provides a controlled flow path between the engagement and disengagement chambers in response to the speed of the clutch, thereby controlling the engagement force of the clutch when the speed of the clutch is equal to or greater than the predetermined speed.

Abstract: A torque converter and lock-up clutch wherein the fluid flow to and from the torque converter is directed into the converter, at an inner location, between the stator and turbine and to the disengagement of the clutch, when the clutch is disengaged. A control valve disposed in the turbine shaft divides the inlet flow. The fluid is exhausted from the converter between the stator and impeller. When the clutch is engaged, fluid flow is directed to the converter between the stator and impeller and the disengagement chamber of the clutch is exhausted. The control valve, during this phase, prevents fluid from exhausting between the stator and turbine.

Abstract: An internal combustion rotary engine oxidizing fluid injection arrangement having a sheet metal liner that is mounted in the engine's exhaust passage and has injection ports through which oxidizing fluid is injected into the exhaust gas in directions transverse to the flow thereof.

Abstract: A torque converter and slipping clutch assembly wherein the clutch engagement force is determined by the torque transmitted by the turbine of the torque converter. The clutch engagement force is controlled by differential pressure on opposite sides of the clutch plate. The pressure on one side of the clutch plate is determined by fluid flow through a variable restriction and a fixed restriction arranged in series. The size of the variable restriction opening changes in response to the torque transmitted by the turbine.
