  • the displacement means coupling part 114 is formed in this embodiment as a radially encircling rotationally symmetrical elevation at the end of the paint needle 109 opposite the paint needle tip 111, so that it can easily engage the paint needle coupling part 113 of the paint needle displacement means 112 and be "gripped" by it.
  • the Farbnadelverlagerungsmitte1112 mounted against rotation on the base 101 and thereby ensures trouble-free insertion of Farbleit responded 104, moves an upper portion of the Farbnadelkupplungsteils 113 in a provided in the base 101 for this purpose guide groove 115.
  • both the paint needle move 109th and the paint needle displacement means 112 along the axial displacement axis 110.
  • the ink inlet portion 108 is for mounting a spray gun cup or, as shown in this embodiment, for mounting a Spray gun cup lid 116 directly to the interchangeable Farbleit issued 104.
  • the interchangeable Farbleit Chinese 104 is also drawn by means of the spray gun cup lid 116 to the main body 101 of the paint spray gun 100 zoom and so fixed to this. This is done by the spray gun cup lid 116, while it is screwed into an internal thread 117 of the paint inlet 108, successively with a provided on the spray gun cup lid 116 depth stop 118 at a designated paragraph 119 of the body 101 is supported.
  • the depth stop 118 on the one hand over-rotation of the mutually corresponding threads of the spray gun cup lid 116 and the Farbleit styles 104 and on the other hand application to high contact forces between the interchangeable Farbleit styles 104 and the base 101 is prevented.
  • the spray gun cup lid 116 is presently a clamping body of a fixing device for fixing or clamping the exchangeable Farbleit prepared 104 relative to the main body 101, wherein the internal thread 117 of the spray gun cup 116 is a first clamping element and the shoulder 119 as a support second clamping element of said fixing device.
  • a retaining ring 120 by means of which on the one hand a Lucasverteilerring 121, a Lsymmetricdüsenring 122 and an air cap 123 on the paint spray gun 100 and on the other hand the interchangeable Farbleit noise 104 on the main body 101 of the paint spray gun 100 are releasably fixed.
  • the air distributor ring 121 and the air nozzle ring 122 are loosely attached to the ink jet area 106 and fixed by means of the retaining ring 120.
  • the air cap 123 is rotatably mounted in the retaining ring 120 by means of a retaining spring, not shown here in detail.
  • a first threaded half 120A is attached to the main body 101 of the paint spray gun 100 and a second threaded half 1208 corresponding to the first threaded half 120A is attached to the exchangeable ink guide 104.
  • the air distributor ring 120 distributes process air supplied by the billet body 101, so that the process air can be provided on the one hand via the air nozzle ring 122 and on the other hand via the air cap 123 at the paint outlet nozzle 106A.
  • the process air guidance within the basic body 101, in particular within the grip region 102, and its control by means of the finger-trigger mechanism, which is not described here, will not be discussed in more detail, since such process air ducts of the prior art arranged in the base body 101 by means of bores (not explicitly numbered here) are known.
  • a leading to the axial displacement axis 109 concentrically circulating process air leading portion 124 is advantageously formed on the one hand by the base 101 and the other by means of the interchangeable Farbleit gear 104.
  • the process air-guiding region 124 is thus divided into two, with a first half of the process air leading portion 124 of the main body 101 of the paint spray gun 100, in particular of the Farbleit adoptedssuit Scheme 103, and another half of the process air leading portion 124 formed by the interchangeable Farbleit responded 104 of the paint spray gun 100 becomes.
  • the region 125 of the main body 101 which is of particular interest in this context has a hatch which differs from the rest of the main body 101, in order to make it clear in the present case that a special main abutment region 126 (see FIG FIG. 15 ) is provided.
  • the main body portion 125 and the remaining main body 101 of the present paint spray gun 100 are made in one piece in this embodiment. However, they can also be divided into two parts in order to be able to attach, for example, differently designed color guide devices 104 to a single main body 101. For this purpose, only the area 125 having the main system area 126 would then have to be exchanged.
  • the air distribution ring 120 comprises a concentric ring seal 127.
  • the concentric ring seal 127 of a range of interchangeable Farbleit responded 104 may be formed.
  • Further ring seals, for example, between the air nozzle ring 122 and the air distributor ring 120 or the ink jet area 106 can be provided if necessary to further ensure the tightness.
  • an explicit illustration has been dispensed with in this case, since sealing regions with such annular seals of the prior art are well known.
  • a receiving groove 128 extending in the main contact area 126 is provided there, ie between the main body 101 and the exchangeable color guide 104 (see also FIG. 15 ), in which, with proper use of the paint spray gun 100 in the present embodiment, a formed by the interchangeable Farbleit noisy 104 seal 129 (see also FIG. 16 ).
  • a receiving groove 128 is provided depending on the shape of the seal 129 can be dispensed with a corresponding with their receiving groove 128. In the present embodiment, however, such a receiving groove 128 is provided.
  • the seal 129 is presently formed by a survey of the replaceable paint spray gun 100.
  • the interchangeable color guide 104 seals the region 124 leading the process air with respect to the main body 101 particularly well and reliably. Since the exchangeable Farbleit responded 104 consists of the plastic body 105, it can particularly well with their collection cling to the main body 101 of the paint spray gun 100, whereby the interchangeable Farbleit responded 104 relative to the main body 101 inherently particularly good sealing properties.
  • the seal 129 extends from the direction of the paint exit nozzle 106A on both sides of the ink inlet 108 and parallel to the axial displacement axis 110 until it is disposed behind the ink inlet 108 transverse to the axial displacement axis 110.
  • the seal 129 can also extend transversely to the axial displacement axis 110 in front of the paint inlet 108, ie between the ink inlet 108 and the ink outlet opening 106A, so that on the one hand the space to be sealed is reduced and on the other hand the paint inlet 108 outside the space to be sealed lies.
  • an additional ring seal 108A on the inner wall of the paint inlet 108 could be dispensed with.
  • the ring seal 108A is provided in this embodiment in order to exclude any compressed air losses along the paint inlet 108 for reasons of safety.
  • the replaceable ink guide 104 can be detachably secured to the main body 101 in a secure and secure manner
  • the replaceable ink guide 104 comprises a counter-abutment region 130, which is essentially mirror-inverted to the abutment surface 126 of the main body 101.
  • the abutment surface 126 has a first planar partial abutment surface 131 and a second partial abutment surface 132, which together form a planar abutment surface of the main abutment region 126.
  • the planar contact surface lies parallel to a plane 133 in which there is an axially displaceable main axis 110 of a color wheel 1109 the paint spray gun 100 extends. After the presentation of the FIG. 15 this level 133 coincides with the paper plane.
  • a structurally simple pre-centering for the replaceable ink guide 104 is provided on the main body 101.
  • the concavely curved contact surface 134 extends along a semicircular arc (not shown here) which radially surrounds the axial displacement axis 110.
  • a concave pre-centering for the interchangeable Farbleit driving 104 is provided structurally simple on the base 101 101 in the direction of the axial displacement axis 110 extending concave.
  • the first plane bearing surface 131 merges into the curved contact surface 134 and the second plane contact surface 132 in a first transition region 135 merges into the curved contact surface 134 in a second transition region 136, the two transition regions 135, 136 extending in the direction of the axial displacement axis 110.
  • the counter investment area 130 comprises a first plane Operaverystrom substances 137 and a second plane Operaurgig.
  • the first plane partial abutment surface 137 and the second plane partial abutment surface 138 together form the plane opposing abutment surface of the exchangeable ink guide 104.
  • the interchangeable Farbleit prepared 104 with its color inlet 108 which projects as a "pin" inclined by the interchangeable Farbleit Vietnamese 104 in the direction of the axial displacement axis 110, can be attached to the main body 101 such that the paint inlet 108 in the body 101 at least a little way projects into the main investment area 126, preferably on the curved contact surface 134, an opening 140.
