摘要： A spring is disposed between first and second reciprocal spool valve elements and arranged to bias the same apart when the level of throttle pressure falls to a low level. The first valve is arranged to control the communication between a source of line pressure and a friction element or elements and is subject to the effects of the governor pressure. The second of the spool valve elements is subject to the effect of throttle pressure and a second spring which biases the second element toward the first one.

摘要： There is provided in an automatic transmission a shift valve which is provided with a plug movable responsive to an engine brake command to hold a valve spool of the shift valve to a downshift position thereof. The plug is designed to supply working hydraulic pressure to an engine brake friction element after it has moved responsive to the engine brake command to hold the valve spool of the shift valve to the downshift position thereof. When the engine brake command is not available, the plug allows the valve spool of the shift valve to move between the downshift position thereof and an upshift position thereof.

摘要： A hydraulic control system comprises a control valve with a solenoid valve operatively connected thereto to modulate the characteristic of hydraulic fluid pressure supplied to a friction element that is to be engaged during a shift in speed ratio. The current supplied to the solenoid is varied in ON/OFF manner in accordance with a duty factor computed by a control unit. The control unit includes a memory storing a map containing various duty factors corresponding to various kinds of shifts and determines an adequate duty factor for a shift which is to take place in the transmission. The characteristic of the hydraulic fluid pressure is modulated during a time period variable with vehicle speed and engine torque which are measured by sensors associated with the control unit.

摘要： In order to stabilize the line pressure developed by a line pressure regulator valve and simultaneously control the operation of a variable capacity pump in a manner that the latter exhibits the desired degree of response to changes in the line pressure, a flow restriction is defined in the bore of the valve itself. This flow restriction is defined between the wall of the bore in which the spool is disposed and a portion of the spool which extends between two adjacent lands and which has a diameter which is slightly smaller than that of the bore.

摘要： Disclosed herein is a hydraulic control system for an automatic transmission which is shiftable from a 4th speed ratio to a 2nd speed ratio. A 2-3 shift valve (24) has a first port (124g) communicating with a first friction unit (C3) and a second port (124h) communicating with a fluid conduit (412) supplied with an actuating fluid pressure. The first port (124g) is allowed to communicate with the first port (124h) when the 2-3 shift valve (24) assumes a downshift position thereof. A 4-3-2 changeover valve (23) is provided which urges a 2-3 shift valve (22) toward a downshift position thereof when a fluid pressure in the first port (124g) increases beyond a predetermined value.

摘要： A hydraulic control system for a lock-up clutch includes a vehicle speed cut valve having a spool movable responsive to a governor fluid pressure between a lock-up position and a non lock-up position. A solenoid valve is provided which is energized such as during coasting of the vehicle or during kickdown operation. When energized, the solenoid valve applies a line fluid pressure to the spool against the governor fluid pressure to forcibly move it to the non lock-up position so as to release the lock-up clutch.

摘要： A lock-up valve includes a spool movable between a clutch engagement position wherein the lock-up clutch is engaged and a clutch release position wherein the engagement of the lock-up clutch is released. A spring biases the spool toward the clutch release position. The spool has a first pressure acting area and a second pressure acting area. A fluid pressure is applied to the first pressure acting area during operation in the m+th speed ratio (where: m is an integer) and the m+1th speed ratio to urge the spool against the spring toward the clutch engagement position. A lock-up timing valve is provided which allows the application of another fluid pressure to the second pressure acting area during shifting between the m th speed ratio and the m+1th speed ratio to urge said spool toward the clutch release position.

摘要： A hydraulic control system comprises first and second shift valves which cooperate with each other to effect a shift between two gear ratios. The first shift valve has a port and two different pressure acting areas which are exposed to pressure from the port depending upon downshift and upshift states of the first shift valve, respectively. The second shift valve effects communication between signal pressure generating means and the port of the first shift valve when the second shift valve is in one of two states to deliver the signal pressure to the port of the first shift valve. A kickdown pressure generating means delivers a kickdown pressure to the first shift valve.
