1. Addition to patent (patent application P 15 33 722.1)

The IJrfindun ^ · relates to an insertable in the telecontrol ira mining, in particular on the hydraulic mine roof and serving for converting a Plüssigkeitsdruckes into an analog pneumatic pressure signal device with a Ilenbran, the ^ uf one side with the fluid pressure and θoren on their arrival J page constant pneumatic pressure of one of its eachlossonic Druol.raumes Ό ο is hit, which has a Ab- tiCdis for the analog signal and a connection for the constant Sulleitungsdruck and from which one opens between the ... connection and the slope, to under the ilembrcn reioliendo drainage hole, which forms a hanging gap with the .. membrane, is led to the outside, according to patent ....... (patent application P 15 33 722.1).

Fluid pressure and the resulting changing Throttling of the drainage hole. Such a device can be miniaturized and is therefore suitable e.g. to display the high fluid pressure in the Pressure chamber of a hydraulic pit ram with the aid of a pneumatic signal.

The main patent used to reduce the annular gap only the deflection of the membrane. The gap width and thus the size of the analog signal is in this Jail does not depend linearly on the fluid pressure. This is disruptive for some technical applications of the device according to the main patent.

The problem of the invention consists in the Subject of the main patent by specifying the smock to train people who are suitable for the relationship between fluid pressure and pneumatic analog pressure signal to match the linearity to a large extent.

According to the invention, these means consist in the fact that under the membrane, in the Druckrauin a support spring with progressive Characteristic is arranged.

This ensures that the membrane bends relatively strongly in the area of low liquid pressures, that with increasing pressures the deflection of the membrane becomes weaker, i.e. the increase in the ZLüssi ^ k <3itsdrucl: it is about one pressure unit one weaker increasing deflection of the I - '. enibran faces »

The larger body of the device has a circular recess 12 which forms a pressure space .. One side of the The pressure chamber is closed off by the membrane 5. The side 5b of the membrane opposite the side 5a is pressurized with compressed air, which is supplied by an internal thread 14 provided bore 15 is introduced into the space 12 via an annular channel 16 under constant pressure » The bore 15 thus forms a connection for supplying the compressed air into the device.

Compared to the connection formed by the bore 15 there is an internal thread / outlet 19 to which the analog signal is sent in a manner to be described arises.

A membrane 5 facing centrally protrudes into the ring channel 12 Send ei-ties tube 20, which is inserted into a corresponding Bore is screwed in at 21 and sealed at 22 with a ring seal. Its screw 23 is used for axial adjustment of the tube in the receiving one Bore and thus to adjust the size of an annular gap 24 ·, which between the free end of the tube 20 and the side 5b of the membrane 5 is formed ». The light one Innenraui ".: 25 of the pipe 2C leads from the chamber 12 to outside in the ALnosphL'.re, '■.

The device "can, for example, be connected to a compressed air line connected to / earth. Then the compressed air flows into the Chamber 12, from there through the clear interior 25 of the tube 20 and thereby enters the atmosphere »

A support spring is located under the membrane "in the pressure chamber with progressive characteristic. The support spring consists of several axially spaced apart gaps clamped parts 40 and 41. For parts 40 and 41 it is spring washers that have a circular ring shape. Accordingly, the spring washer 40 has an annular opening 43; the spring washer 41 has an annular extension 42. The expansions 42 and 43 differ in terms of their diameter. In the seal of the spring travel these take up diameter, so that the diameter of the recess 43 is smaller alε dor the recess 42 is.

Fluctuations in the fluid pressure on the side 5a of the l-Ienibran 5 initially lead to a deflection of the membrane and to reduce the size of the annular gap 24. As a result, the outflow of the compressed air from the chamber 12 is more or less heavily involved. As a result, air pressure builds up in u31 'chamber 12, which can be removed at 19 «
