Abstract

The invention relates to a connecting device (1) which consists of a connecting nipple (5) having an annular ring (7) and a compression sleeve (15). The aim of the invention is to provide a particularly compact connecting device. For this purpose, the compression sleeve (15) has a connecting area (16) with a substantially square cross-section which is forced onto the annular ring by pressure. The securing area axially fastens the compression sleeve to the connecting nipple (5), however, without engaging behind it, i.e. it is not provided with a section that extends beyond the annular ring (7). The connecting device (1) is therefore especially compact in the axial direction and allows for a bigger sealing length. The overall length of the connecting device (1) is exclusively determined by the length of the peripheral surface (6) serving for sealing in relation to the axial length of the annular ring (7). The connecting device does not require any additional sections engaging behind the annular ring (7).

Description

technical field

[0001] The invention relates to a connection device for connecting a hose to a fluid-carrying line. Background technique

[0002] In vehicle technology—but also for other applications—it is always important to connect hoses to pipes, connection fittings of components such as pumps, coolers, and the like. This is difficult at least when the space for establishing the connection or the connection itself is small, in particular the space available in the longitudinal direction of the hoses to be connected is small. On the other hand, it is precisely in vehicle technology that hose connections are permanently sealed even under unfavorable conditions, such as corrosive attack, temperature fluctuations and mechanical loads such as vibrations. Such a connection is in particular a nipple-hose connection for attaching a connecting nipple to a hose. Such nipple connections cannot be too long in the axial direction. Contents of the invention

Embodiment Construction

[0019] FIG. 1 shows a connection device 1 via which a hose 2 , in particular a hose 2 for conducting fluid, is connected to a component 3 , such as an oil-conducting component configured as a coolant compressor, such as a hydraulic device etc. The hose 2 and the assembly 3 enclose a fluid-conducting channel 4 . This channel runs through a connecting nipple 5 - which is shown separately in FIG. 2 . The connection nipple is substantially tubular and encloses a fluid channel (not shown in detail) which extends from one end side to the other. The connecting nipple has a cylindrical shell surface 6 on the outside, which can also be designed in a frusto-conical shape. But in this case, the cone angle is very small. On one end of the cylindrical shell 6, precisely on the end facing away from the hose, an annular flange 7 is formed on the connection nipple 5, the shape of which can be seen from FIG. 5 detail. The annular flange has a substantially arcuate cross section and a heig...
