Control valve for a device for changing the control times of an internal combust ion engine
First Claim
1. A control valve for a device for changing the control times of an internal combustion engine, the control valve comprising:
- a substantially hollow-cylindrical valve housing, a control piston arranged within the valve housing and displaceable axially in the valve housing, a pressure medium connection, two operating connections, at least one tank connection, the operating connections, the pressure medium connection and the tank connection all being formed as respective radial connections, wherein the operating connections may be connected to the pressure medium connection and the tank connection due to axial displacement of the control piston within the valve housing, wherein in the axial direction of the control valve, the connections are arranged in the sequence;
pressure medium connection, tank connection, operating connection, operating connection.

Abstract
A control valve for a device for changing the control times of an internal combustion engine, having a substantially hollow-cylindrical valve housing, a control piston which is arranged within the valve housing and can be displaced axially, a pressure medium connection, two operating connections, and at least one tank connection. The operating connections, the pressure medium connection and the tank connection are formed as radial connections. It is possible for the operating connections to be connected to the pressure medium connection and the tank connection by axial displacement of the control piston within the valve housing. The operating connections are arranged adjacently.
