Abstract

In a device (1) for actuating an overflow valve (5), in particular an overflow valve (5) incorporated in a return line (4) of a feed pump (2) and comprising a valve housing (6) and a valve body (7), the valve housing (6) of which is inserted in a fixed position in a housing (3) of the feed pump (2), with a compression spring (8) arranged between the valve housing (6) and the valve body (7) of the overflow valve (5) and a joining piece (11) attached to the valve body (7) of the overflow valve (5), with the joining piece (11) projecting from the valve housing (6) of the overflow valve (5) and having a position switch (12) assigned to the feed pump (2) held onto it via an adapter (9) which is fixed into the housing (3) of the feed pump (2), both the axial adjustment of the overflow valve (5) and the actuation of the control electronics of the feed pump (2) should be undertaken using a common housing (2); in addition, it should be possible for the procedures for assembling and dismantling the components of the device (1) to be carried out quickly and uncomplicatedly. This is achieved by arranging electrical, pneumatic, hydraulic and/or mechanical components for controlling the feed pump (2) inside the adapter (9), and because these components can be actuated by the position switch (12) using a control surface (38) running in a circumferential direction.
