摘要： A shock absorber includes a shock absorber main body composed of a vehicle-body side tube and a wheel side tube and formed with a lubrication clearance, a damper including a cylinder, a piston which partitions the interior of the cylinder into two working chambers, and a rod, a reservoir chamber composed of an air chamber and a working fluid chamber, a partition wall member for partitioning the working fluid chamber into an upper working fluid chamber and a lower working fluid chamber, a flow path having a check valve for permitting only a movement of the working fluid from the upper working fluid chamber to the lower working fluid chamber, and a communication path for allowing communication between the lower working fluid chamber and the lubrication clearance. A cross-sectional area of the lubrication clearance and that of the rod are different.

摘要： A fluid pressure pump motor includes a supply/discharge passage where both a hydraulic fluid pumped in to a fluid pressure pump and a hydraulic fluid discharged from the fluid pressure motor flow, and a variable valve provided in the supply/discharge passage to control the fluid path area of the supply/discharge passage. The variable valve reduces the fluid path area of the supply/discharge passage for simultaneously actuating the fluid pressure pump and the fluid pressure motor to be smaller than the fluid path area for actuating only one of the fluid pressure pump and the fluid pressure motor.
