Oil pressure regulating valve

Regarding a valve with an adjustment structure applied to hydraulic pressure, it is particularly applicable to a bicycle hydraulic brake system.

The application of hydraulic brakes to bicycles is currently a very popular brake system. The main purpose of hydraulic brakes is to use a hydraulic master cylinder to fill with brake fluid and connect to the brake pipe, and the brake master cylinder has a piston that is moved by the brake handle to make When the piston moves in the brake master cylinder, part of the brake oil is pushed through the brake pipe to the hydraulic brake caliper, so that the piston of the hydraulic brake caliper pushes the disc, and then the disc rubs against the disc, and the disc rotating with the wheel will Kinetic energy is converted into heat energy to meet the demand for deceleration or stop.

When the brake handle is pressed, the piston located in the hydraulic master cylinder pushes the brake oil to the hydraulic brake caliper, and there will be an idle stroke before the braking effect is generated. The aforementioned short idle stroke can be called the braking action with high zero sensitivity. The aforementioned long idle stroke can be referred to as low braking sensitivity. However, the aforementioned idling strokes are different due to personal preferences. Generally speaking, they can only adapt to the idling strokes of various manufacturers. For this reason, many manufacturers have developed settings that can adjust the grip distance corresponding to the idling stroke, or for braking The master cylinder has developed adjustable idle strokes such as Taiwan invention patent I409191 hydraulic grip, I636907 hydraulic brake master cylinder, and Taiwan's new patent M560429 full hydraulic brake master cylinder. However, in order to have the idle stroke for adjusting the hydraulic brake, it is not only troublesome and wasteful to replace the entire original brake master cylinder.
