Hydraulic unit for a slip control system of a hydraulic vehicle brake system
A hydraulic unit for a slip control system of a hydraulic vehicle brake system comprises a hydraulic block including a socket, a first port, a pressure change damper, and a second port. The socket has a base and defining a first interior. The first port is located at the base of the socket. The pressure change damper defines a second interior and is positioned in the socket in engagement with the first port. The first port is in fluidic communication with the second interior. The second port is in fluidic communication with the second interior via a portion of the first interior outside of the pressure change damper.
1. A hydraulic unit for a slip control system of a hydraulic vehicle brake system, comprising:
a hydraulic block including a socket, the socket having a base and defining a first interior;
a first port located at the base of the socket;
a pressure change damper positioned in the socket in engagement with the first port defining a second interior, the first port being in fluidic communication with the second interior; and
a second port in fluidic communication with the second interior via a portion of the first interior outside of the pressure change damper,
wherein the pressure change damper includes at least one check valve hydraulically positioned between the first port and the second port,
wherein the at least one check valve includes two check valves hydraulically connected in parallel,
wherein one of the two check valves is springless, and
wherein another of the at least two check valves is spring-loaded.
2. The hydraulic unit according to claim 1 , wherein:
the first port defines a circumference; and
the pressure change damper projects into the first port and rests against the circumference.
3. The hydraulic unit according to claim 1 , wherein the pressure change damper rests sealingly on the first port.
4. The hydraulic unit according to claim 1 , wherein the at least one check valve is positioned hydraulically at an outlet of the pressure change damper.
5. The hydraulic unit according to claim 1 , wherein the pressure change damper includes a restrictor hydraulically positioned between the first port and the second port.
