係合装置用アキユームレータ。 An accumulator for a hydraulically actuated frictional engagement device that communicates with an oil path to a hydraulically actuated frictional engagement device of an automatic transmission for a vehicle to alleviate shock when the frictional engagement device is engaged, a cylindrical accumulator piston that receives the hydraulic pressure of the oil passage to the frictional engagement device as an accumulator positive pressure and receives an accumulator back pressure that opposes the accumulator positive pressure, and is provided with a partition wall in an axially intermediate portion; a first member having a first opening into which the accumulator piston is assembled and a first cylinder chamber into which the accumulator piston is slidably fitted; an aquicum back pressure spring that presses the partition wall and biases the acumulator piston in a direction toward the first opening in opposition to the aquium positive pressure; an accumulator positive pressure spring that biases the accumulator piston in a direction away from the first opening so as to oppose the accumulator back pressure; and a second accumulator having a second opening.
a second member having a cylinder chamber formed therein and assembled to the first member with the second opening facing the first opening; A support piston that supports the cylinder, and a hydraulic pressure introduction oil passage that opens into the second cylinder chamber and receives hydraulic pressure that operates the support piston to compress the accumulator positive pressure spring. Accumulator for hydraulically operated friction engagement device.
