Abstract

PURPOSE: To simplify the device by a method wherein the cross sectional area of a control piston is made larger than that of a balance piston and the parting distance of a fail-safe clip is rendered to be smaller than the stroke of the control piston.
CONSTITUTION: A control piston 10 constitutes a proportional valve, together with a control spring 14, a valve body part 11 and a valve seat 12. A balance piston 20, the parting distance of which from the control piston 10 is limited to S2 by being connected with the fail-safe clip 17, constitute a trailing type valve together with a valve body part 21 and a valve seat 22. The stroke of the control piston 10 is rendered to be S1 and the relationship S1>S2 is established. Furthermore, the cross sectional area A1 of the control piston 10 is made larger than that A2 of the balance piston 20. When something wrong at the trailing side, the proportional valve is actuated by the difference of the cross sectional areas. When something wrong at the control side, the balance piston 20, being applied with the control spring 14, acts as a limiting valve, resulting in doubling the control pressure.
