摘要： A valve part of a hydraulic control valve for controlling flows of pressurized medium is provided, wherein the valve part includes a cylindrical valve housing with a first cylinder casing section extending in the axial direction and a first cylinder base section extending perpendicular to the axial direction, with the sections defining a valve housing hollow space that is open on one side. 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 is held in the valve housing hollow space so that it can move in the axial direction, and has a second cylinder casing section extending in the axial direction and a second cylinder base section extending perpendicular to the axial direction, with these sections defining a control piston hollow space that is open on one side. The second cylinder casing section adjacent to the second cylinder base section is provided with a radial 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 manner to the pressure connection and to the discharge connection through axial displacement of the control piston. The valve part is distinguished in that the discharge connection of the control piston includes at least one inclined opening, having a wall direction that assumes an angle of less than 90° to the axial direction.

摘要： A rocker arm (1) for a valve train of an internal combustion engine which is pivoted on a support pin (10) about its axis (9), whereby a push rod (7) contacts one end section (5), and the valve shaft (8) of a gas exchange valve contacts the other end section (6). The mounting of the rocker arm (1) on the support pin (10) takes place through two radial roller bearings (16) spaced at a distance from each other, whereby in a manner in accordance with the invention, an additional axial roller bearing (17, 18) is incorporated into the rocker arm bearing arrangement to prevent sliding friction.
