Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a casing for a compressed air conditioner having a flow passage guided across a storage chamber, the inlet and outlet of the flow passage having the same axis on opposite sides. The invention also relates to a type in which the device is arranged in such a way that it is likewise provided on opposite sides with a bayonet-type mounting member on one side and a screw-type mounting member on the other side. Such compressed air regulators are designed, for example, as steam separators, pressure regulating valves and filter pressure reducers and are installed in compressed air lines in order to further purify the compressed air or to determine the pressure state. Known devices of this type have hitherto had different housings.

The object of the invention is to use the same form for all three devices, namely the steam separator, the pressure regulating valve and the filter/pressure reducer, in which case the finished parts are adapted accordingly and the device itself To provide a casing for a compressed air conditioner that can be manufactured at low cost.

In order to solve such problems, the present invention
In the area of the bayonet mounting element a snap-type connection element and in the area of the screw-in mounting element a guide cylinder are arranged; in the case of use in a steam separator, the bayonet attachment element has a catch plate; The snap-on connection has a filter with an enclosed bell, the screw-on connection has a cover cap connected to it, and the bayonet connection has a closed closure when used as a pressure regulating valve. The cover is
A pressure spring member having a spring collar guided in a guide cylinder and a valve body connected to the spring collar is coupled to the screw-in mounting member, and when used in a filter or pressure reducer, a bayonet is attached. The snap-fitting member has a saucer, the snap-fitting coupling member has a filter having an enclosed bell-shaped member, and the screw-fitting member has a spring collar guided in a guide cylinder and a valve connected to the spring collar. A pressure spring member having a body is connected to the pressure spring member. With this format, casings can be manufactured in large numbers,
The expenditure on molds for complex plastic casings is thus simply saved. Similarly, the bearing holder is simplified and the assembly parts are unified.

The invention will be explained below with reference to the exemplary embodiments shown.

The casing is made of plastic and has the shape of a hexahedron with an approximately square base. The casing has a flow passage 1, an inlet 2 of which is provided on one side 3 and an outlet 4 on the other side 5, the inlet 2 and the outlet 4 having the same axis. It is arranged as follows. A receiving chamber 6 is provided in the flow channel 1 between the inlet 2 and the outlet 4 , and is connected to the outlet 4 via a valve seat opening 7 . In the area of the receiving chamber 6, the housing is designed as a snap-on connection element 8, which consists of a rim of an elastic tab 9.

The casing is finished on the lower side 10 for a bayonet fitting 11 and on the upper side 12 for a threaded fitting 13. On the other sides 14, 15 there are cutouts 16, 17 forming side walls 18 in the casing.
The side walls 18 are each provided with an opening 19 whose axis 20 lies parallel to the axis 21 of the flow channel 1 . In the side wall 18 along the side surface 5, in the area of the opening 19, a retaining groove 22 is provided for the non-rotatable reception of a nut 23. As can be seen in FIG. 1, in this way several housings are flanged together in block fashion, so that different devices can be easily connected to each other and the flow channels 1 of the individual devices can be directly connected to one another. .

If the compressed air preparation consists of a vapor separator 41 (FIGS. 5 and 6), a cover cap 24 is screwed onto the screw-on fitting 13, in which case a sealing element 25 is suitable. Consideration has been given to the seal. Bayonet type mounting member 1
1 is equipped with a saucer 26, and a bell-shaped member 27 is engaged with the snap-type coupling member 8.
A filter 28 is housed within the bell and a housing cylinder 3 is housed within the head portion 29 of the bell.
0, and the housing cylinder has a through-hole 31
surrounded by. A notch 32 is formed around the head portion 29, and the tongue piece 9 is locked in the notch. Bell-shaped member 2
A torsion disk 34 is provided in the extension 33 of 7, which is held in a non-rotatable manner there and whose axial play space is defined by the end side 35 of the elastic tongue 9. It is restricted. Starting from the head part 29 is a concentric pin 36 into which the filter 28 with a hole 37 is inserted. The saucer 26 supports a rib 38, and a valve disc 39 is abutted against the end surface of the rib. A spring 40 surrounding the pin 36 is tightened between the filter 28 and the valve disk 39. Steam separator 4
1, the guide cylinder 42 provided on the upper side 12 is of no importance in the area of the screw-on mounting element 13.

If the compressed air regulator is designed as a pressure regulating valve 51 (FIGS. 7 and 8), a closing cap 43 is mounted on the bayonet mounting 11, which supports the receiving cylinder 30. A pressure spring element 44 is connected via the screw-in mounting element 13 to the adjusting head 4.
I support 5. A spring collar 46 guided into the pressure spring element 44 via an adjusting head 45 is moved in the axial direction, so that the initial spring force of the pressure spring 47 can be adjusted from the outside, such that one end of the pressure spring 47 , supported on a spring collar 48 guided in a guide cylinder 42. Accommodation cylinder 3
A valve body 49 is guided in the spring 0 and is connected to the spring collar 48 via an extension 50 . The extension 50 in this case passes through the valve seat opening 7.

When the filter/pressure reducer 52 is formed (FIGS. 9 and 10), the screw-type mounting member 1
A pressure spring element 44, such as in the case of a pressure regulating valve, is connected via 3, and a receiver 26, such as in the case of a steam separator 41, is connected via a bayonet mounting element 11, and a corresponding The bell-shaped member 27 is attached to the filter 28 within the snap-type coupling member 8.
and are connected in a snap-type manner. As soon as the compressed air flows through the inlet 2 and then through the filter 28 around the bell 27 and then through the valve seat opening 7 to the outlet 4, the valve body 49 is lifted from the valve seat. . This occurs if the pressure of the pressure spring 47 exceeds the pressure of the fluid medium. The pressure state is influenced via the regulating head 45, so that the pressure in the flow channel 1 or the connected line can be determined as desired.

In short, the same plastic casing is used for the three embodiments of the compressed air conditioner,
As a result, this plastic casing can be produced in large numbers and easily stored.
The individual devices have only a few individual parts that are easily completed and quickly assembled via connecting parts.
