Description

Purge control valve for cars}

The present invention relates to a vehicle purge control valve, and more particularly, to simplify the manufacturing process of the purge control valve installed between the canister and the intake manifold to control the input and output of the evaporated gas to reduce the production cost and simplify the production process. It relates to a funnel control valve of a vehicle.

A common purge control solenoid valve is a device installed between the canister and the intake manifold to induce fuel evaporation gas that is evaporated from the fuel tank and moved to the canister to the intake manifold.

As shown in FIG. 1 or FIG. 2, the purge control valve of the vehicle according to the related art opens a multi-stage inlet hole 101 therein, while forming a multi-stage coupling jaw 102 at one end of the inner circumference thereof. Polygonal blocking plate 201 on one side to selectively open and close the case 100 and the inlet hole 101 of the case 100 coupled to the opening and closing plate 110 to form the discharge hole 111 to be And forming the inner part 202 to be inserted into the communication hole 302 of the opening and closing plate 110, and controlling the pressure into the main spring 210 between the opening and closing plate 110 and the blocking plate 201. The communication hole 302 is formed to form the inner jaw 301 to be coupled to the pin 200 and the coupling jaw 102 of the case 100 and communicate with the discharge hole 111 of the opening and closing plate 110 therein. ) Is formed in multiple stages, and the inside of the communication hole 302 is formed with a cap 300 containing the subspring 310. The.

The purge control valve 10 as described above is installed between the canister and the intake manifold to prevent negative pressure in the intake manifold to maintain a constant pressure at all times. In the canister, the evaporated gas is purged through the canister pipe (1). When input to the inlet hole 101 side of (10) by pushing the blocking plate 201 of the pressure control pin 200 by the pressure of the boil-off gas into the inlet hole (101).

The pressure regulating pin 200 is moved by the evaporation gas to the inlet hole 101 and is elastically moved only when the evaporation gas is above a predetermined pressure by the main spring 210.

The boil-off gas is not connected to the blocking plate 201 formed in a triangle at the inner circumference of the cylindrical inlet hole 101 while pushing the blocking plate 201 of the pressure control pin 200 into the inlet hole 101. As the evaporation gas is moved through the moving passage 120, the intake manifold pipe is discharged to the communication hole 302 side of the cap 300 through the discharge hole 111 of the opening and closing plate 110 and connected to the final intake manifold side ( 2) the boil-off gas is moved.

At this time, when the boil-off gas is overloaded, the boil-off gas of which the pressure is high is completely pushed the pressure control pin 200 into the inlet hole 101 of the case 100 to block the plate 201 of the pressure control pin 200. The discharge hole 111 of the opening and closing plate 110 is sealed to block the evaporated gas supplied from the canister from being overloaded to the intake manifold side.

However, the conventional purge control valve 10 as described above is formed between the inner periphery of the inlet hole 101 of the case 100 and the opening and closing plate 110 of the pressure control pin 200 to move the evaporation gas. In order to form 120, the blocking plate 201 of the pressure control pin 200 may be formed in a polygonal shape through a separate processing process on the circular blocking plate 201 during the initial manufacturing. According to the process of cutting the outer circumference of the metal blocking plate 201 so that the production cost and manufacturing process of the purge control valve 10 was added.

Therefore, the main object of the present invention is to produce a product by simplifying the manufacturing cost and manufacturing process of the purge control valve by using a pressure control pin accommodated inside the case of the purge control valve as a circular plate and forming a separate moving passage in the inner periphery of the inlet hole of the case. To provide a vehicle purge control valve that can reduce the cost.

First, as shown in FIG. 3 or 4, the purge control valve of the vehicle according to the present invention forms an inlet hole 101 therein, while partially communicating in the longitudinal direction with the inner circumference of the inlet hole 101 at equal intervals. The case 100 and the case 100 combined with the opening and closing plate 110 to form a discharge hole 111 by forming a moving passage 120 and a multi-stage coupling jaw 102 formed at one open end; The inlet hole 101 is formed in the inner periphery to form a circular blocking plate 201 on one side so as to selectively open and close the through hole by the pressure of the evaporation gas, and the other side communication hole 302 of the opening and closing plate 110 Forming an inlet 202 to be embedded in the pressure control pin 200 and the main spring 210 is inserted between the opening and closing plate 110 and the blocking plate 201, and the engaging jaw 102 of the case 100 The inner jaw 301 is formed to be coupled to the) and to communicate with the discharge hole 111 of the opening and closing plate 110 therein While forming the communication hole 302 in multiple stages, the interior of the communication hole 302 is composed of a cap 300 containing the sub-spring 310.

The moving passage 120 of the case 100 is formed in the longitudinal direction at the inner circumference of the inlet hole 101 of the case 100 while linearly forming the shape to partially communicate with the inlet hole 101 in the longitudinal direction. It is formed at equal intervals on the inner circumference of the inlet hole (101).

In addition, the metal pressure control pin 200 is formed by the circular plate to form the shape of the blocking plate 201 to shorten the processing process for forming a conventional triangular shape of the next inlet hole of the case 100 ( 101) Sliding at the inner circumference.

Referring to the operation of the present invention is as follows.

First, when the evaporation gas is supplied from the canister side to the intake manifold side, when the evaporation gas is input to the inlet hole 101 of the purge control valve 10 through the canister tube 1, the pressure is controlled by the pressure of the evaporation gas. The blocking plate 201 of the pin 200 is slid into the inlet hole 101.

When the pressure control pin 200 is moved into the inlet hole 101 by the evaporation gas, the blocking plate 201 of the pressure control pin 200 which blocks the communication between the canister tube 1 and the inlet hole 101. While the seal is released, the evaporation gas introduced into the inlet hole 101 is moved to the linear moving passageway 120 formed in the longitudinal direction at the inner circumference of the inlet hole 101, and the communication hole 302 of the cap 300 is moved. After passing through, it is supplied to the intake manifold side.

At this time, when the evaporated gas supplied from the canister has a high pressure, the pressure regulating pin 200 presses the main spring 210 while pressing the main spring 210 to the discharge hole 111 of the opening / closing plate 110. 202 is inserted to block the supply of the boil-off gas to prevent the load of the boil-off gas supplied to the intake manifold side.

Here, the main spring 210 allows the boil-off gas to flow into the moving passage 120 while compressing it according to the strength of the boil-off gas, and when the pressure of the boil-off gas is low, it is elastic to its original state. The restoring plate 201 of the pressure adjusting pin 200 blocks the inlet hole 101 of the case 100 communicating with the canister tube 1 to restore the supply of the evaporated gas that is moved from the canister to the intake manifold side. Block it.

Furthermore, the subspring 310 housed inside the cap 300 is an end portion of the inlet portion 202 of the pressure regulating pin 200 that is inserted into the communication hole 302 side of the cap 300 by the overpressure of the boil-off gas. By being elastically compressed by the pressure to mitigate the impact of the pressure control pin 200 sliding in the case 100.

As such, the blocking plate 201 of the pressure adjusting pin 200 may be formed of a plastic material without having to be processed into a triangle so that the moving passage 120 may be formed inside the inlet hole 101 of the case 100 in the shape of a circular plate. By injection molding the moving passage 120 inside the case 100 to be manufactured, there is an effect of reducing the manufacturing cost of the purge control valve 10 and simplifying the processing process.
