The invention relates to a safety device (2) for interrupting a gas flow within a gas-conducting device (1). An inertia body (32) moves from a resting position in the case of an acceleration above a specifiable acceleration threshold value acting on it. Due to the movement, the inertia mechanism (3) activates a reaction mechanism (4), which interrupts the gas flow within the gas-conducting device (1). In this process, the safety device (2) is free of gas flowing through it.

A diaphragm 30 includes a fixed portion 32 to be fixed to a body portion 10, and a flexible thin film portion 33 integrally connected to the fixed portion 32. The fixed portion 32 has a tubular press-fitting portion 34 to be press-fitted into a tubular sealing groove 15 formed on the body portion 10, and a diaphragm-side tapered surface 38 formed on an axis C side with respect to the press-fitting portion 34. In a state where the press-fitting portion 34 is press-fitted into the sealing groove 15, an inclination angle θ1 of the diaphragm-side tapered surface 38 relative to the axis C is smaller than an inclination angle θ2 of a body-side tapered surface 18 formed on the body portion 10 relative to the axis C, and an end portion 38a of the diaphragm-side tapered surface 38 is brought into contact with the body-side tapered surface 18.

Sealing means are disclosed for preventing the ingress of water and dirt between a brake caliper and the carrier guide pin. At the end of the guide pin facing away from the brake carrier, a retaining clip holds a sealing bead of a sealing boot at least partially within an axial bore of the guide pin. At the end of the guide pin which faces towards the carrier, a sealing boot is provided seated on a ring which in turn is attached to the caliper. The other end of the sealing boot is attached to the guide pin, in a space between the guide pin and the ring. The sealing means at either end are compact, and provide effective sealing where there is not enough space to provide known sealing means.

Described is a method for manufacturing a diaphragm assembly through the use of injection molding. The method can avoid the use of PTFE as a chemically resistant coating. Further, the method can increase overall adherence of a polymer diaphragm to an insert through the use of an interference surface on at least the surface of a head of the insert.

A sealing comprises a seal portion and a plate portion fixed to the seal portion. The seal portion can have an undulating configuration of at least one peak and at least one valley, and the plate portion can circumferentially surround the seal portion. The seal portion can be made of a first material and the plate portion can be made of a second material more rigid than the first material. The seal portion can have a radially inward facing contact surface that defines a central opening of the sealing.

A diaphragm seal for transmitting the pressure of a process medium includes a main body having a surface and a separating membrane secured to the surface, thereby forming between the separating membrane and the surface a pressure chamber which communicates, via an opening in the surface, with a hydraulic path. The separating membrane can be exposed to the process medium on a first side, and the separating membrane has a central middle region. The diaphragm seal further includes a temperature transducer for determining a temperature measurement variable of the process medium, which is secured in the middle region on a second side of the separating membrane, and the main body is joined to the separating membrane such that a transmitting fluid, which fills the pressure chamber and the hydraulic path, does not come into contact with the temperature transducer.

An accumulator membrane is disclosed. The accumulator membrane may include a generally cylindrical tube having a side wall with a first end a second end. A lip may be located at the first end, and may form a pocket with the side wall. An extension may protrude from the second end at an angle generally perpendicular to the lip and co-axial with the generally cylindrical tube.
