Definitions
- the present invention is a Handabschaltpistole according to The preamble of claim 1, as for example from DE-A-44 28 634 is known.
- Object of the present invention is therefore a Handabschaltpistole of mentioned type in such a way that they are reliable and also easier to handle.
- FIG. 1 schematically shows a cross section through a manual shut-off pistol 1 according to FIG of the invention.
- the handshake gun 1 has two substantially mirror-symmetrical to one another and appropriately arranged Housing shells 5 on. In the figure, only one of these housing shells 5 shown.
- the two shells 5 define a closed housing, the one Front wall 6, a rear wall 7, a bottom wall 8 and an end wall 9 has.
- the high-pressure medium is supplied via a high-pressure hose 4 through a receiving opening 3 of a buckling protection sleeve 2 in the manual shutdown pistol entry.
- the high pressure hose 4 is on a neck of a nipple 10 with a compression sleeve 11 is sealingly held.
- the high-pressure medium is then through the manual shutdown gun 1 a spray tube 16 supplied.
- the corresponding terminal 12 is shown in Figure 2 and in the modified embodiment shown in Figure 3.
- a valve housing 13 is provided with the an inner bore 14 is provided with a conical end 15.
- the spray tube 16 is screwed into a nipple 17, which in turn from a Fixing nut, consisting of an outer part 18 and an inner part 19th is overruled.
- the nipple 17 in this case has a projection 26, to which a corresponding Approach 29 of the inner part 19 can create.
- a seal 27 For sealing in the bore 14 is a seal 27, preferably an O-ring provided.
- the fastening nut consisting of the components 18, 19, is preferably made of two made of separate materials.
- the inner part 19 is preferably a metallic one Material, which then with a plastic material to form the outer part 18th is overmoulded.
- the contact surface between the outer part 18 and the inner part 19th Can be wavy, jagged or otherwise to increase adhesion be educated.
- the inner part 19 is provided with an internal thread, which is an external thread on the valve housing 13 corresponds. Accordingly, the inner part 19 with the help of the outer part 18 are screwed.
