Problems solved by technology

[0006] However, the conventional check valve 1 has a complicated appearance and is difficult to assemble because it is manufactured with functionality in mind alone.
More specifically, as figure 1 As shown, the valve housing 2 has the disadvantage of high manufacturing costs due to its complex shape and large product size and can only be produced by cutting
The traditional check valve 1 has the disadvantages of many parts, long assembly time and low assembly reliability because of its structure in which the spring leaf 6 is press-fitted onto the valve housing 3

Abstract

Disclosed herein is a check valve of a brake system to enable easy processing and assembly through a simplified structure. The check valve for brake systems includes a valve sheet housing press-fitted to a step of a hydraulic block provided with an oil passage, the valve sheet housing including an upper part having an opening and a lower part having an open / close hole to form an oil channel in an inner part, a ball provided in the valve sheet housing to open or close the oil channel, and a spring to elastically support the ball, wherein the valve sheet housing is provided in the upper part thereof with a plurality of fixing protrusions that protrude in an inside diameter direction along a circumference of the opening to support the spring.

Description

technical field [0001] Embodiments of the present invention relate to a brake system check valve so that processing and assembly can be easily performed with a simplified structure. Background technique [0002] A braking system for braking must be installed on the vehicle. In recent years, in order to obtain stronger and more stable braking force, various systems have been proposed. Examples of braking systems include anti-lock braking systems (ABS) that prevent wheel slip during braking, brake traction control systems (BTCS) that prevent drive wheels from slipping during sudden vehicle acceleration, and Vehicle Dynamics Control (VDC) is a vehicle dynamics control system (VDC) that combines the brake system and the brake traction control system to control the brake hydraulic pressure to maintain the driving state of the vehicle smoothly. [0003] These electronically controlled braking systems consist of a number of solenoid valves that control the brake hydraulic pressur...
