摘要:
A holder (2) for fastening a component (3), in particular a fuel distributor (3), via a holding element (7) to an internal combustion engine (4) comprises decoupling elements (8, 9), a fastening body (5) and a fastening means (6). Here, the fastening body (5) is fastened by means of the fastening means (6) to the internal combustion engine (4). Furthermore, the holding element (7) is fastened via the decoupling elements (8, 9) to the fastening body (5). Moreover, a prestressing element (10) is provided which is connected to the fastening body (5), wherein a prestress of the decoupling elements (8, 9) is set by way of a predefined arrangement of the prestressing element (10) relative to the fastening body (5), in which predefined arrangement the connection of the prestressing element (10) to the fastening body (5) takes place. Furthermore, a system (1) having a holder (2) of this type is specified.
摘要:
The invention relates to a mounting (2) for fuel injection systems (1), which is used to connect a fuel injection valve (17) to a fuel-guiding component (3), comprising a connecting body (5) and a connecting piece (9) which are interconnected. A receiving chamber (15) is formed inside the connecting body (5) and the connecting piece (9), in which a fuel nozzle (16) of the fuel injection valve (17) is at least partially arranged. The connecting piece (9) comprises an inner collar (12). The invention also relates to an elastically deformable element (27). Said elastically deformable element (27) is at least indirectly supported on the inner collar (18) of the connecting piece (9). Also, the fuel nozzle (16) is supported at least indirectly on the elastically deformable element (27). The invention also relates to a fuel injection system comprising said type of mounting (2).
摘要:
A connection element (2) for fuel injection systems (1) is used to connect a fuel injection valve to a fuel-conducting component. A main body (4) having a receiving space (15), into which a fuel connecting piece (3) of the fuel injection valve can be introduced, and a fastening element (5) are provided. At least one cut-out (17-20) is made in a wall (21) of the main body (4) that surrounds the receiving space (15), the fastening element (5) being introduced at least partially through the cut-out (17-20) into the receiving space (15) to fasten the fuel connecting piece (3) to the main body (4). At least one elastic bearing element (27-30; 27') is also provided, the fastening element (5) that is introduced partially through the cut-out (17-20) into the receiving space (15) being supported on the wall (21) of the main body (4) by means of the elastic bearing element (27-30; 27'). A fuel injection system (1) having a connection element (2) of this type is also specified.
摘要:
An arrangement (1) which serves in particular as a fuel injection system for high-pressure injection in internal combustion engines comprises a fuel distributor (2) and multiple fuel injection valves (3, 4). Here, each of the fuel injection valves (3, 4) is arranged on a cup-like element (9, 10) of the fuel distributor (2). At least one of the fuel injection valves (3, 4) is fastened to the associated cup-like element (9, 10) by way of a retention element (15). The retention element (15) has a support surface (16). The cup-like element (9) has, on an underside (20), a contact surface (21) by which the cup-like element (9) is supported, via a damping layer (11), on the support surface (16) of the retention element (15). The retention element (15) is fixed to the cup-like element (9). The fuel injection valve (3) also has a collar (25) which is supported on the retention element (15). Damping of vibrations, and thus a reduction in noise emissions, is possible by means of the damping layer (11).
摘要:
A bearing bush (5) for a holder (3), said holder being used for fastening a fuel distributor (2) to an attachment structure (6), comprises a first bush part (11) and a second bush part (12). The first bush part (11) has a rigid bush body (13) and a damping element (14) that is firmly bonded to the bush body (13) of the first bush part (11). The second bush part (12) has a rigid bush body (15) and a damping element (16) that is firmly bonded to the bush body (15) of the second bush part (12).
摘要:
A holder (3) serves for fastening a distributor tube (4) of a fuel distributor (2) to an add-on structure (5). The holder (3) comprises a first half shell (15) and a second half shell (16). An elastically deformable damping element (20) is injection moulded onto a holding region (17) of the first half shell (15). Furthermore, an elastically deformable damping element (22) is injection moulded onto a holding region (18) of the second half shell (16). For the fastening of the distributor tube (4) to the add-on structure (5), the half shells (15, 16) are joinable to each other in such a manner that the half shells (15, 16) surround the tubular component (4) and hold the tubular component (4) by means of the elastic damping elements (20, 22). The first half shell (15) and the second half shell (16) can be connected to each other here by means of a film hinge (28). A further configuration possibility consists in that the damping element (20, 22) is inserted into the relevant half shell (15, 16).
