| 摘要 |
The invention relates to a control valve element, comprising a valve housing (1), through which a displaceable adjusting element (2) extends, which carries a cylindrical piston-shaped control element (3) at the end thereof that is removed from the valve housing (1). According to the invention, the control element (3) comprises at least one central passage (4), a central chamber (5) into which one end of the central passage (4) leads is designed between the valve housing (1) and the control element (3), the central chamber (5) is delimited by an inner partial region of the back surface of the control element (3) located opposite of the face, the central passage (4) has a central mouth (47) at the face (31) of the control element (3), a peripheral chamber (8) that is sealed with respect to the central chamber (5) is designed between the valve housing (1) and the back surface of the control element (3), the control element (3) has a spaced peripheral passage (7) which at one end opens into the peripheral chamber (8) and at the other end thereof opens into the face (31), and the mouth (77) of the peripheral passage (7) is spaced from the mouth (47) of the central passage (4) at a predetermined radial distance (A). |
