Patent ID: 8118060

Claim:
Valve part of a control valve for controlling flows of pressurized medium, the valve part comprising: a cylindrical valve housing with a first cylinder casing section, which extends in an axial direction and which comprises a valve housing hollow space, the first cylinder casing section is provided with a first work connection, a second work connection, and a pressure connection, each of which open into the valve housing hollow space, a cylindrical control piston held in the valve housing hollow space so that it can move in the axial direction which includes a second cylinder casing section extending in the axial direction and a second cylinder base section extending perpendicular to the axial direction, wherein the second cylinder casing section and the second cylinder base section at least partially define a control piston hollow space, the second cylinder casing section, adjacent to the second cylinder base section, is provided with a discharge connection opening into the control piston hollow space, and the control piston is constructed such that the work connections can be connected selectively in a fluid conducting way to the pressure connection and to the discharge connection through axial displacement of the control piston, and the discharge connection of the control piston comprises at least one inclined opening, having a wall direction that assumes an angle of less than 90° relative to the axial direction, wherein the inclined opening is angled in an outward direction away from the valve housing in a direction toward the second cylinder base section.
