Device for keeping two adjacent rooms separated by means of a membrane.

The invention relates to a device for keeping apart two adjacent rooms of the same or different pressure by means of a movable membrane Made of elastic material, which is firmly clamped around the circumference and in the middle between machines or device parts and is provided with supports.

In the case of actuators for valves or in the case of others as membrane cylinders trained adjustment devices are known on the one hand, the use of plate-shaped membranes. These generally only allow a relatively * small stroke too. In the case of larger strokes, the membrane is sometimes considerably stressed by stretching. on the other hand it is known to use so-called roll diaphragms. A larger stroke is possible with the rolling diaphragm. Weng. However the membrane is essentially cylindrical at the inner or outer clamping, the inner circumferential surface of the cylinder becomes outward when it is unrolled put inside. This leads to a considerable stretching of the

In this way, a membrane is obtained with a; shaped loop or half-wave running under a gentle arc, which has a large stroke the membrane allows in relation to the diameter. The half-wave molded into the membrane remains Change in stroke of the diaphragm, i.e. the clamping points in the given design, constant. When executing

This ensures that the membrane does not stretch or compress when the stroke changes. This results in a membrane that can be thick enough to withstand high operating pressuresa without the membrane practically flexing.

Wise thick membranes that are extremely durable.

The membrane according to the invention can expediently be assigned support parts whose support surfaces are in the Cross-section seen - roof-shaped at the same cone angle to each other and to the membrane a. The support parts are expediently brought together « For this purpose, the support parts can slide into one another by means of toothing, e.g. by means of tongue and groove.

In the example of use of Mg. 2 and 3 on a diaphragm valve, the diaphragm 1 is between the valve body 1o and the spindle housing 11 clamped. The inner restraint 3 consists of a cladding of the Core 12 of the closure piece, which is moved up and down by means of the spindle 13 and the handwheel 14 can. At point 3, the membrane is clamped in a circular shape.

The membrane itself has a fabric insert 15> Support parts can be assigned to the membrane 1.

The support parts 16 and 17 are to be designed so that they - seen in cross section - with the conical surfaces 18 and 19 run roof-shaped to one another.
