Abstract

A valve insert (8a, 8b) for a valve, in particular for a control valve (2) for controlling pressure-medium streams of a camshaft adjuster, includes an insert housing (10), in which a filter (12) and a non-return valve (14) with a closing element (24) and a seat element (20) are integrated. A configuration of the valve insert which is easy to install is ensured by at least the insert housing (10), the filter (12) and the seat element (20) being connected non-detachably to one another and forming one pre-assembled structural unit (40).

Claims

1. A valve insert for a valve, comprising an insert housing in which a filter and also a non-return valve are integrated with a closing element and a seat element, wherein at least the insert housing, the filter and the seat element are connected to each other in a non-detachable way and form a preassembled structural unit.

2. The valve insert according to claim 1, wherein the closing element has a flat construction and covers an opening in the seat element in a fluid-tight way in a closed position.

3. The valve insert according to claim 1, wherein the seat element has a contact surface, and openings are formed around a periphery of the contact surface.

4. The valve insert according to claim 3, wherein a collar that is provided with the openings is constructed around the contact surface.

5. The valve insert according to claim 4, wherein a filter frame of the filter is injection molded around the contact surface.

6. The valve insert according to claim 3, wherein the contact surface is part of the insert housing.

7. The valve insert according to claim 5, wherein the insert housing forms the filter frame.

8. The valve insert according to claim 7, wherein the collar is a Z-shaped collar that is injection molded from a material of the insert housing.

9. The valve insert according to claim 1, wherein clips for a snap-on connection to the valve are formed on the insert housing.

10. A valve, comprising a valve housing with a hollow construction and with at least one feed connection (P) and at least one discharge connection (T), and a valve insert according to claim 1 is mounted on the valve housing.

11. The valve of claim 10, wherein the valve is a control valve for controlling flows of pressurized medium in a camshaft adjuster.
