Japanese Patent JP2545575
Kind Code:
B2
Abstract:
PURPOSE:To make improvements in responsiveness in a check valve by installing a working fluid feed passage and the check valve so as to be individually interconnected to a tank and respective suction and discharge ports of each pump case, in an automobile 4WD system. CONSTITUTION:In this driving coupler 10, a working fluid is fed to a suction side chamber out of respective suction and discharge ports 21a, 21b, 22a, 22b, 23a, 23b of each of pump cases 21-23 from a tank 30a, but respective working fluid feed passages 24a-24x, 25a-25c and check valves 33a-33c, 34a-34c, 35a-35c, 36a-36c for the pump direction are installed so as to be individually interconnected to respective suction and discharge ports of these pump cases 21-23. Therefore length of each working fluid feed passage is shortened and thereby flow passage resistance is reduced, while a working fluid quantity in each working fluid feed passage is also reduced, so that each check valve can be formed in compact in size. Thus, improvement in responsiveness of the check valve is well promoted and, what is more, system miniaturization can be made possible.
