Liquid pressure booster

Abstract

Abstract PURPOSE:To eliminate demand of severer dimensional accuracy than necessary level for each part constituting a liquid pressure booster by bearing a supporting lever through a supporting tool for regulating stopping position of valve body in a liquid pressure control valve. CONSTITUTION:A spool 26 in a spool valve 28 engages with one end of a control lever 25 while the other end of the control 3 ever 25 engages with a power piston 5, and the stopping position of the spool 26 is determined corresponding to the position of a supporting lever 24 journaled to the control lever 25. The supporting lever 24 is born on a housing 1b through an eccentric rod 7. Consequently, stopping position of the spool 26 can be regulated through a regulating section 7a to a predetermined position. Dimensional error or fluctuation of parts constituting a liquid pressure booster 20 can be absorbed through regulation of the eccentric rod 7 and does not influence onto the stopping position of the spool valve 28.
