摘要： A control valve pressurizes an outlet conduit when a variable fluid pressure signal rises above a first predetermined level and depressurizes the outlet conduit when the variable signal subsequently drops below a second level that is lower than the first level, the valve further functioning to maintain the outlet conduit unpressurized without regard to the variable fluid pressure signal level in the absence of a second fluid pressure signal. The control valve automatically controls a fluid pressure operated lock-up clutch of a torque converter in a vehicle transmission system. The variable fluid pressure signal source may be a governor producing a pressure proportional to vehicle speed while the second fluid pressure signal source is one or more of the transmission drive conditioning devices. The control valve then functions to engage the lock-up clutch to eliminate fluid drive from the vehicle power path at higher vehicle speeds while at higher gear settings but maintains the fluid drive, regardless of vehicle speed, when the transmission is at one or more of the lower speed settings. These control functions are accomplished with a simplified and economical spool valve construction which exhibits a reliable and pronounced hysteresis or snap action to avoid undesirable oscillations in switching the torque converter in and out of the vehicle drive line.

摘要： A transmission control system is provided for use with a transmission assembly having a torque converter which couples a power input member with a transmission speed ratio section. A lock-up clutch is provided to selectively bypass the torque converter and couple the input member directly with the transmission speed ratio section. Some systems provide converter lock-up and lower transmission control pressure resposive to positioning of the transmission speed selector valve while others require additional complicated controls to operate the lock-up clutch of the converter and reduce transmission control pressure relative to the vacuum level of the prime mover. In the subject arrangement, a single valve (112) that is responsive to the output speed of the transmission (10) simultaneously actuates the lock-up clutch (32) of the torque converter (14) and lowers the operating pressure level of a dual stage pressure relief valve (72) by directing a fluid pressure signal to an actuating chamber (106) of the dual stage pressure relief valve (72). This arrangement ensures that the output speed of the transmission is operated at a sufficient low torque level before the lock-up clutch is actuated and furthermore does not require numerous complicated controls to lower the transmission control operating pressure and actuate the lock-up clutch.

摘要： Inching valves for providing controlled slow movement of a vehicle normally have a valve mechanism therein to control the pressure level of the fluid being directed to the driving clutch of the vehicle. Upon release of the pedal, a sudden jerk of the vehicle may occur. The modulating inching valve of the subject arrangement provides a housing having a valving mechanism slidably disposed therein and operative to selectively block communication between an inlet port and an outlet port. The modulating inching valve further includes an input actuator mechanism operative to selectively control the valve mechanism in response to the position of the operator's inching pedal. Through a portion of a predetermined travel distance of the input mechanism the operator controls the rate of pressure being supplied to the fluid actuated device and during the remaining portion of the predetermined travel distance the modulating relief valve automatically controls the rate of pressure rise. The modulating inching valve provides a compact arrangement allowing selective control of the pressure level to the fluid actuator device at lower torque levels within the clutch but inhibits the operator'3 s ability to control the rate of pressure rise to the clutch during higher torque levels. This eliminates undue heat and abnormal wear of the elements and further eliminates the tendency of the vehicle to jerk if the inching pedal is fully released quickly.
