Abstract

PURPOSE:To increase the working force of a liquid pressure cylinder by installing a small diameter piston with a check valve in the major piston for less oil consumption and applying the oil pressure through the check valve in the last stage of strokes. CONSTITUTION:When the pressure in a pressure chamber 7 is raised by letting a master cylinder 6 operate, the pressure in the pressure chamber 14 of an oil hydraulic cylinder 1 is increased. As this oil pressure allows a piston 12 to push a pad 3, a disc 2 makes contact with pads 3, 4. The pressure oil in the pressure chamber 14 can not, in the initial stage of strokes, open a valve poppet 23 of a check valve to flow into No.2 pressure chamber 15. As No.2 pressure chamber 15 becomes at negative pressure, oil is supplied from a reserver 38 through a valve poppet 39. At the finishing stage of strokes, a valve poppet 14 of the check valve opens to allow the pressure oil to flow into a recess 18 of No.2 piston 13, and the piston 12 is pushed at the whole area.
