Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-2, the utility model discloses a relief pressure valve stop piece for automobile brake, including deciding body 1, magnetism-isolating pipe 2, reset spring 3 and kinetoplast 4, kinetoplast 4 is installed in magnetism-isolating pipe 2, magnetism-isolating pipe 2 is fixed with deciding 1 lower part of the body, reset spring 3 installs between deciding body 1 and kinetoplast 4, decide 1 cold heading shaping of the body, it has the arch 5 of two symmetries to decide 1 bottom surface of the body, arch 5 is used for providing the magnetic field route, two arch 5 middle zone provide the installation space 6 of spring, the passageway that forms between two arch 5 is fluid flow space 7.

The shape of the protrusion 5 is a sector.

The magnetism isolating pipe 2 is welded and fixed with the lower part of the fixed body 1, so that the fixed body 1 is ensured to be more firm.

The mover 4 is installed in the magnetism isolating pipe 2 and can move axially, and the magnetism isolating pipe 2 provides a space for guiding the mover 4 to move, so that an important component for the operation of the electromagnetic valve is formed.

In the initial state, the head of the movable body contacts with the conical surface of the valve seat below due to the action of the return spring 3, and the electromagnetic valve is in a closed state. When the coil is electrified, the moving body is acted by electromagnetic force to overcome hydraulic pressure and spring force to move upwards, so that the oil passage of the electromagnetic valve is opened.

Decide 1 cold-heading shaping of body, decide 1 bottom surface processing of body and have two symmetrical archs 5 for provide the magnetic field route, can also install the spring, machining efficiency is high, low in production cost.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
