Abstract

PURPOSE: To make the device compact by method wherein a control valve controlling the inlet liquid pressure of one channel, moving in correspondence to the pressure against a spring, on one hand, and an open-and-shut valve synchronized with the opening and shutting of the control valve and inserted in the liquid-presssure route of the other channel, on the other, are provided opposedly on both sides of a free piston.
CONSTITUTION: A liquid-pressure control valve fof 2-channel piping has a proportioning vlave (control valve) P and a speed-reduction degree sensing type valve G within its main body 1. The main body 1 has staged transparent orifices consisting of orifices 1a, 1b and 1d and an orifice 1c in parallel with the orifice 1b, while the valve P is provided with a plunger 3 and a poppet valve 10 both fitted slidably in the orifice 1b. In this case, a free piston 24 is put in the orifice 1d and chambers 31 and 32 formed thereby on both sides thereof are communicated with liquid routes 7 and 35, respectively. On one side of the free piston 24 opposite to the valve P, an open-and-shut valve 36 of a poppet valve type which is communicated with and blocks up properly the route between an inlet port 37 and an outlet port 38 is arranged, is linked to the valve P.
