## Abstract

A valve subassembly for arrangement on a valve device is disclosed. The valve subassembly includes a valve closing body configured to be placed on and raised from an associated valve seat. The valve subassembly also includes a return element configured to reset the valve closing body against the valve seat and a valve cover configured to close an associated valve housing. The valve cover, the return element, and the valve closing body are connected to one another in a captive manner.

## Claims

### Claim 1

A valve subassembly for arrangement on a valve device, the valve subassembly comprising:
a valve closing body configured to be placed on and raised from an associated valve seat;
a return element configured to reset the valve closing body against the valve seat; and
a valve cover configured to close an associated valve housing,
wherein the valve cover, the return element, and the valve closing body are connected to one another in a captive manner.

### Claim 2 (depends on 1)

The valve subassembly according to claim 1, wherein:
the valve cover is coupled in a captive manner to the return element, and
the return element is coupled in a captive manner to the valve closing body.

### Claim 3 (depends on 1)

The valve subassembly according to claim 1, wherein the return element is a helical spring.

### Claim 4 (depends on 1)

The valve subassembly according to claim 1, wherein the return element has a spiral shape.

### Claim 5 (depends on 1)

The valve subassembly according to claim 1, wherein the return element is secured on an elevation provided on the valve cover.

### Claim 6 (depends on 5)

The valve subassembly according to claim 5, wherein the elevation has a cylindrical configuration.

### Claim 7 (depends on 1)

The valve subassembly according to claim 1, wherein the valve closing body is connected positively to the return element.

### Claim 8 (depends on 7)

The valve subassembly according to claim 7, wherein the positive connection is formed by an overmolding.

### Claim 9 (depends on 1)

The valve subassembly according to claim 1, wherein the return element is connected nonpositively to the valve cover.

### Claim 10 (depends on 1)

The valve subassembly according to claim 1, wherein the valve subassembly is configured for use in a pump element.

### Claim 11 (depends on 10)

The valve subassembly according to claim 10, wherein the pump element is a hydraulic unit of a vehicle brake system.

### Claim 12 (depends on 5)

The valve subassembly according to claim 5, wherein the return element is configured to be pulled onto the elevation on the valve cover.
