Abstract
A flat, box-shaped hydraulic block for the mechanical fastening and hydraulic interconnection of solenoid valves, pump elements, etc. of a slip-controlled vehicle brake system connects connections of installation spaces for the pump elements to connectors for a brake master cylinder and connections of receptacles for pressure build-up valves which run past one another via flat chambers on longitudinal sides of the hydraulic block and short blind bores. As a result, the receptacles of the pressure build-up valves are connected to the connectors for the brake master cylinder. The chambers damp pressure pulses of the pump elements of a piston pump.
Claims11
A box-shaped hydraulic block for a slip-controlled vehicle brake system comprising:
- an upper side;
- an underside;
- two transverse sides;
- two longitudinal sides;
- a plurality of wheel brake connectors defined next to one another on one of the two transverse sides of the hydraulic block;
- a plurality of brake master cylinder connectors defined on the underside of the hydraulic block;
- a plurality of pressure build-up valve receptacles defined next to one another on the upper side of the hydraulic block;
- a plurality of installation spaces for pump elements of a piston pump;
- a plurality of pressure build-up valve receptacle connections;
- and
- one installation space connection between each brake master cylinder connector of the plurality of brake master cylinder connectors and a pressure side of a corresponding installation space of the plurality of installation spaces,
- wherein the wheel brake connectors are defined below the brake master cylinder connectors,
- wherein the installation space connections connect the brake master cylinder connectors and the installation spaces to a pressure build-up valve receptacle, and
- wherein the installation space connections extend through to an other transverse side of the two transverse sides of the hydraulic block opposite the one transverse side.
