Abstract

PURPOSE: To stabilize the output characteristic for the input shaft by arranging an elastic body easily deformable to a reaction disc and allowing the dimension allowance to be absorbed.
CONSTITUTION: When a poppet valve 9 is switched, and a thrust due to differential pressure is applied onto a power piston 3, and an output is generated on an output shaft 12, a repulsive force corresponding to said output is applied onto the output shaft 12 and compresses an elastic element 10. At this time, as the projected part 10a of the elastic element 10 has a small contact area with the step part 3g of a power piston 3, and the surface pressure acting on said contact part is high, the elastic element is deformed by a small repulsive force at the first, and the whole elastic element 10 is shifted. Thus, in initial operation, the front end part 7b of a plunger 7 projects by the dimension allowance from the front end surface of the step part 3g.
