Abstract

PURPOSE: To make a varied-angle controlling apparatus relatively small and reduce the quantity of control conduits by using a control cylinder equipped with a piston and having different pressure-receiving areas as the varied-angle controlling apparatus of a variable capacity type liquid pressure motor.
CONSTITUTION: When a manual selector valve 11 is turned to the position opposite to the drawing, the higher pressure between liquid pressure pumps P1 and P2 is selected by a shuttle valve 10 and is fed to the chamber 22 of a control cylinder 20. The pressure receiving area S2 of the chamber 22 of the control cylinder is larger than that S1 of a chamber 23, and a piston 21 is shifted leftward in proportion to the discharge pressure of the liquid pressure pump P1 or P2, and thus, the angle of the swash plate of a liquid pressure motor 5 is controlled.
