Further, be interference fit between described Chang Kaijia pressure electromagnetic valve and normally closed vacuum solenoid valve and the described body, and realize sealing, so both saved seal ring, guaranteed system's reliability under high pressure again.
Further, the exit end of described normally closed vacuum solenoid valve is connected with low pressure poultry energy device, described low pressure poultry can be positioned in the middle of the described body end face by device, and two described normally closed vacuum solenoid valves connect a described low pressure poultry energy device, and the low pressure poultry can be used for storing the braking liquid that flows back in the brake cylinder by device.
Further, described low pressure poultry can be adopted the spring piston chamber by device, can change the volume of low pressure poultry energy device, and simple and compact for structure.
Further, described low pressure poultry can be connected with the backflow plunger pump by device, and described backflow plunger pump is positioned at described body left and right sides both ends of the surface, and the backflow plunger pump can be carried back master brake cylinder to the braking liquid that stores in low pressure poultry energy device, for recycling of brake system.
Further, described backflow plunger pump connects throttling buffer, and described throttling buffer is positioned at described backflow plunger pump rear side, and energy disperser can obviously alleviate the pulsatile impact of backflow plunger pump, makes the braking liquid smooth flow of output.
The utility model has reached the purpose of automotive wheel anti-lock owing to adopted technique scheme, the stability of vehicle when having increased brake, and this device inner structure is simple, compact simultaneously, the reliability height.
