## Abstract

Receptacles for a pressure-change damper and for a throttle are provided, at an offset to each other and at an offset to a receptacle for a hydraulic pump, in opposite sides of a hydraulic block for a hydraulic assembly of a traction control system of a hydraulic vehicle braking system, whereby a greater volume of the pressure-change damper and thus better damping are possible.

## Claims

### Claim 1

A hydraulic block for a hydraulic assembly for a slip control system of a hydraulic vehicle braking system, comprising;
receptacles for valves of the slip control system;
a receptacle for a hydraulic pump;
a receptacle for a pressure-change damper in one side of the hydraulic block; and
a receptacle for a throttle in another side of the hydraulic block.

### Claim 2 (depends on 1)

The hydraulic block according to claim 1, wherein the receptacle for the pressure-change damper and the receptacle for the throttle are arranged in opposite sides of the hydraulic block.

### Claim 3 (depends on 2)

The hydraulic block according to claim 2, wherein the receptacle for the pressure-change damper and the receptacle for the throttle have parallel axes.

### Claim 4 (depends on 1)

The hydraulic block according to claim 1, wherein the receptacle for the pressure-change damper and the receptacle for the throttle are arranged at an offset in relation to one another.

### Claim 5 (depends on 1)

The hydraulic block according to claims claim 1, wherein the receptacle for the pressure-change damper and the receptacle for the throttle intersect one another or open into one another.

### Claim 6 (depends on 1)

The hydraulic block according to claim 1, wherein the receptacle for the pressure-change damper and/or the receptacle for the throttle are arranged at an offset in relation to the receptacle for the hydraulic pump.

### Claim 7 (depends on 1)

The hydraulic block according to claim 1, further comprising:
a bored element configured to (i) connect a delivery side of the hydraulic pump arranged in the receptacle for the hydraulic pump to the receptacle for the pressure-change damper, and (ii) connect the delivery side of the hydraulic pump arranged in the receptacle for the hydraulic pump and/or the receptacle for the pressure-change damper to the receptacle for the throttle.
