Title:
COUNTER-RECOIL SEQUENCE VALVE AND SEQUENTIAL DRIVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/119775
Kind Code:
A1
Abstract:
A counter-recoil sequence valve and a sequential driving method therefor. The counter-recoil sequence valve comprises: a reciprocating plunger cylinder (1), a first hydraulic cylinder group and a second hydraulic cylinder group. Each hydraulic cylinder group comprises two hydraulic cylinders (11, 12, 13, 14). The reciprocating plunger cylinder (1) is connected to one hydraulic cylinder of each hydraulic cylinder group by means of an oil passage port at an end and an oil pipe connected thereto, and the reciprocating plunger cylinder (1) is connected to the other hydraulic cylinder of each hydraulic cylinder group by means of an oil passage port at a side wall and an oil pipe connected thereto. A communicating pipe is connected between the two oil pipes connecting the two hydraulic cylinders of each hydraulic cylinder group. A one-way valve (9, 10) is provided on the communicating pipe. The counter-recoil sequence valve can form a counter-recoil two-position, four-way sequence valve, and multiple counter-recoil two-position, four-way sequence valves are connected in series or in parallel can form a non-electromagnetic servo automatically controlled hydraulic unit, such as a legged hydraulic robot alternate stepping mechanism, and a fuel pressurization and injection mechanism with valves of a four-cylinder, four-stroke internal combustion engine being sequentially opened and closed and linked.
