Embodiment Construction

[0055] will refer to Figure 1 to Figure 6a A combined device 1 according to the invention and according to a first exemplary embodiment is presented. The combined device 1 comprises a housing 2 and a flange 3 having a first flange side 4 facing the housing 2 and a second flange side 5 opposite thereto. A collar 6 inserted into a connector opening 7 of the flange 3 is formed on the housing 2 . In this example, the collar 6 is press-fitted into the connector opening 7 by press-fitting, and is additionally fastened to the flange 3 by means of a laser-welded connection (not shown in more detail). Two assembly openings 8 , the latter being through holes like the connector opening 7 , are formed on the flange 3 . For the sake of clarity, the assembly opening 8 and the details described in the context adjacent thereto or therewith are each designated with the same reference signs. Two recesses 34 (where in each case one recess 34 extends in an uninterrupted manner on the circumfe...

Abstract

The invention relates to a combination (1) comprising a housing (2) and a flange (3) which has a first flange side (4) and a second flange side (5) opposite the first flange side. The combination (1)comprises a collar (6) which is either part of the housing (2) or is secured to the housing (2), and the collar (6) is inserted into a connection opening (7) of the flange (3). The flange (3) has at least one first assembly opening (8) which is formed at a distance from the connection opening (7). In order to advantageously develop the combination, a depression (34) which runs around the at leastone assembly opening (8) is formed in the flange (3) on the first flange side (4). The depression (34) has an inner edge (35) which runs laterally along the entire circumference of the depression at adistance (x) from the assembly opening (8). The invention further relates to an assembly which comprises an aforementioned combination (1), a housing (18), in particular a cylinder head housing of amotor, and screws (19) for assembling the combination (1) on the housing (18).

Description

technical field [0001] The present invention relates to a combination comprising a housing and a flange having a first flange side and an opposite second flange side, wherein the combination comprises a collar which is part of the housing or Fastened to the housing with the collar inserted into the connector opening of the flange, wherein the flange has at least one first assembly opening configured with a spacing from the connector opening. Background technique [0002] The housing associated with such a combination may for example be the housing of a high-pressure gasoline or diesel pump (eg a single piston pump). In the axial fixing of the single-piston pump and the servo valve to another housing, for example to the housing of the cylinder head on the engine, it is intended to prevent tilting by means of the flange of the combination. For example, the flange is welded to the pump housing or the servo housing and fastened to the motor housing by means of two screws. Sinc...
