Definitions

• the invention relates to a damper according to the preamble of claim 1.
• the invention is therefore based on the object of providing a generic damper for connecting a sanitary fitting, which allows simple and easy-to-install installation of the damping element.
• This object is achieved by the characterizing features of claim 1: by the divisibility of the housing, one side of which can be opened axially to such an extent that the damping element can be inserted axially in the rigid capsule without elastic deformation after it has been placed in the temporarily opened capsule has been.
• Their insertion into the housing creates a connection between the two, which allows the external shape of the housing of the fitting connection to be designed independently of the shape of the damping element required in each case.
• Fig. 1 shows a central longitudinal section through the first embodiment of a connecting piece with damper cartridge, in half
• Fig. 3 shows a central longitudinal section through the second embodiment of a connector for single-hole fittings, with damper cartridge
• Fig. 4 shows a cross section along the line IV - IV in Fig. 3 through the cartridge of the second embodiment
• the two damper cartridges of both embodiments differ in the mutual connection of their two identical halves 10.1 and 10.2 or 110.1 and 110.2 of a dimensionally stable capsule 10 or 110 for receiving an afluid damping element 12, which consists of an elastomer with closed pores and with its circular cylindrical Tube shape completely fills the cavity, which is formed on the one hand by the capsule and on the other hand by an elastic piece of hose 14 which carries water during operation and is acted upon by water sound.
• an afluid damping element 12 which consists of an elastomer with closed pores and with its circular cylindrical Tube shape completely fills the cavity, which is formed on the one hand by the capsule and on the other hand by an elastic piece of hose 14 which carries water during operation and is acted upon by water sound.
• Each capsule 10 or 110 consists of a circular-cylindrical jacket 16 or 116 divided in its center and two parallel, one- or two-part annular disks 18 arranged in radial planes, the bore edges of which encompass the outer circumference of the tube piece 14, whereby they touch two flange-like sealing beads 20 present at the ends axially inside, which are acted upon by the two annularly closed end sections 22.1 of a circular-cylindrical, rigid support tube 22 with axially parallel, elongated slots 22.2 radially outward. Through these slots 22.2, the pressurized tap water reaches the inner circumference of the hose section 14, which interacts with the damping element 12 like a series connection of two springs, the characteristics of which are appropriately coordinated.
• the two shell-shaped halves 110.1 and 110.2 of the capsule 110 divided along the axis by means of the same snap connections 124 connected to each other, each consisting of hook 124.1 and eyelet 124.2, as shown in Fig. 4; these can be located in pairs in the radial central plane of the capsule 110 or at its two ends or can extend over the entire length of the capsule.
• each of the two damper cartridges is an integral structural unit of the Capsule 10 or 110 with the damping element 12, the hose section 14 with sealing beads 20 and the support tube 22 with strands 22.2 is Se.
• This unit is handled as a whole and inserted into a housing 26 or 126 of the fitting connection which encloses it before it is screwed on by means of a threaded ring 28 or 128 with an externally offset external thread 30 or 130 for a union nut indicated in FIG on the central water channel 32 and 132 along the axis is sealed watertight.
• both the housing 26 and 126 on the one hand (on the side of the cartridge that is remote from the threaded ring) and the threaded ring 28 and 128 on the other hand each have two mirror-image radial inner shoulders 34 and 36 and one of two identical circumferential inner surfaces 38 and 40, against which one of the two sealing beads 20 rests; in the case of the inner surfaces under pressure by the support tube 22, so that there is water tightness.
• the housing 26 or 126 Since the housing 26 or 126 has a rectangular cavity profile, in which the threaded ring 28 or 128 is also involved, and the cartridge fits exactly, it is not only the outer peripheral surface of the damping element 12 that lies on the inner peripheral surface of the capsule 10 or 110, but also their outer peripheral surface on the inner peripheral surface of the housing; in addition, one of the two capsule disks 18 bears against a radial inner surface 27 or 127 of the housing, while the other disk 18 bears against the radial inner surface 28.1 or 128.1 of the screwed-in threaded ring 28 or 128.
• the cavity formed by the housing 26 or 126 and the threaded ring 28 or 128 radially outside the water channel 32 or 132 is therefore completely filled by the cartridge.
• the first embodiment of the damper is integrated in a connecting piece which, according to FIG. 1, the housing 26 and on the right thereof the threaded ring 28 with a recessed external thread 30 for screwing on a union nut on the fitting side, and to the left of the housing 26 a connection piece 42 with an external thread for screwing into wall-side pipe end with internal thread.
• the second embodiment of the damper is integrated in a similar connecting piece which, according to FIG. 3, comprises the similar housing 126 and above it the functionally similar threaded ring 128 with a stepped external thread 130 and below the housing 126 a connector 144 with an internal thread.
• Fig. 3 is also indicated by dash-dotted lines that in this embodiment, the connection of a so-called single-hole fitting to a wall-side corner valve via the connection piece shown with built-in damper in cartridge form is intended.
• the first embodiment of the damper can also be used in connection with the variant of the connection piece from FIG. 1 shown in FIG. 2, in which its threaded ring 28 with an external thread 30 by the combination of an intermediate ring 46 screwed into the housing 26 and one in the latter screwed support ring 48 is replaced, on which a union nut 50 sits loosely, which is screwed to the valve.
