Embodiment 1

[0042] Embodiment 1: Reciprocating two-position four-action sequence valve.

[0043] Such as figure 1 As shown, the reciprocating sequence valve of the present invention includes a reciprocating single-acting plunger cylinder 1, a negative pressure shuttle valve 2, a second hydraulic cylinder group and a first hydraulic cylinder group.

[0044] The plunger cylinder 1 includes a cylinder body and a plunger arranged inside the cylinder body, and the plunger and the cylinder wall form a seal at all coupling sections to avoid oil leakage. The top of the cylinder body is opened to form an end oil passage, and a side wall oil passage is provided on the side cylinder wall of the cylinder body. When in use, the plunger in the plunger cylinder 1 can be synchronously linked with the piston of the internal combustion engine in the same direction to provide power for the sequence valve.

[0045] The shuttle valve 2 includes a housing and a valve core 3 arranged inside the housing. The v...

Embodiment 2

[0051] Embodiment 2: Sequential driving method of reciprocating sequence valve.

[0052] The sequence driving method of the re-entry sequence valve of the present invention comprises the following steps:

[0053] 1. Set the reentry sequence valve as described in Embodiment 1. When the machine is shut down, the spool 3 of the negative pressure shuttle valve 2 is located on the left side of the inner cavity of the valve body, and the right oil port connected to the first oil pipe 4 is in the In the open state, the left oil passage connected to the third oil pipe 6 is in the closed state.

[0054] 2. The plunger in the plunger cylinder 1 is controlled to go upward, and the hydraulic oil enters the first hydraulic cylinder 11 through the end oil port, the shuttle valve 2 and the first oil pipe 4 (because the third oil pipe 6 is blocked at this time), And push the piston in the first hydraulic cylinder 11 to act upwards (because the activation pressure of the second reset device 1...

Embodiment 3

[0060] Embodiment 3: The method of using the double-position two-position four-action sequence valve on an internal combustion engine.

[0061] The method for using a reciprocating sequence valve on an internal combustion engine comprises the following steps:

[0062]1. The re-entry sequence valve described in Embodiment 1 is installed on the internal combustion engine, the plunger in the plunger cylinder 1 and the piston of the internal combustion engine are synchronously linked in the same direction, and the first reset device 15 is linked with the first group of valves of the internal combustion engine , the second reset device 16 is linked with the first group of fuel pump plungers of the internal combustion engine, the third reset device 17 is linked with the second group of valves of the internal combustion engine, and the fourth reset device 18 is linked with the second group of fuel pump plungers of the internal combustion engine; stop , the spool 3 of the negative pre...

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.

Description

technical field [0001] The invention relates to a hydraulic valve, in particular to a reciprocating sequential valve and a sequential driving method thereof. Background technique [0002] The gas distribution and fuel boost injection of the existing internal combustion engine belong to two systems, and the power transmission and transformation forms of these two systems mainly contain two kinds, one is mechanical, and the other is electromagnetic. The mechanical type converts the rotary motion into the reciprocating motion of the valve stem or fuel pump plunger by the cam mechanism, while the electromagnetic type converts the rotational mechanical energy into electrical energy by the generator, and the electrical energy is converted into magnetic force through the electromagnetic coil, and then drives the valve stem or fuel pump. Nozzle valve. Both of the above two forms have the following disadvantages: the power has been transformed many times, and the self-consumption en...
