The first electrode includes a first portion and a second portion, wherein the first portion of the first electrode is supported by the canister top, and the second portion of the first electrode is configured to extend into the fluid collection chamber. The second electrode includes a first portion and a second portion, wherein the first portion of the second electrode is supported by the canister top, and the second portion of the second electrode is configured to extend into the fluid collection chamber. The sensor also includes an electric circuit configured to detect an electrical property associated with the first and second electrodes.

A switching valve having a valve seat with a longitudinal axis (L) and having a valve plate with a valve plate surface which can be placed into a pass-through position, in which the switching valve is open, and into a closed position, in which the switching valve is closed and the valve plate bears with the valve plate surface, in a contact region, against the valve seat, wherein the valve plate has a modulus of elasticity of at least 1000 N/mm.sup.2, which switching valve is characterized in that the valve plate, in the closed position, is deformed by a closing force acting thereon, in such a way that the contact region of the valve plate surface in the closed position forms an angle α, which differs from 0°, with the contact region of the valve plate surface in the pass-through position.

A pressure relief valve includes a bowl-shaped housing having a bottom wall and an annular sealing wall, wherein the sealing wall delimits a valve through-opening, and a jacket wall. A cover is provided for covering a housing opening of the housing opposite to the bottom wall, having a diaphragm holder extending in the direction of the bottom wall. A diaphragm is provided for covering the valve through-opening, wherein the diaphragm is connected to the diaphragm holder and disposes the diaphragm holder sealingly on the annular sealing wall such that the valve through-opening is closed.

A pressure relief valve assembly includes a carrier, a valve, and a baffle. The carrier includes a first end and a second end. The first end defines a first opening. The second end defines a second opening. The carrier defines a flow passage extending from the first opening to the second opening. The valve is supported by the carrier and is operable in an open position and a closed position. In the open position, the valve permits a flow of fluid through the first opening. In the closed position, the valve inhibits the flow of fluid through the first opening. The baffle is disposed in the flow passage. The baffle and the carrier collectively define a flowpath extending through the flow passage.

The present invention relates to a valve device characterized in that it comprises a valve component and a membrane component. The valve component comprises a bottom cover with one or more first apertures; a top cover with one or more second apertures, wherein the bottom cover and the top cover enclosing a venting chamber; a plate accommodated inside the venting chamber and being pressed by one or more projections attaching to the top cover against the one or more second apertures on the bottom cover; and wherein silicon oil is provided between the bottom cover and the plate; and wherein the plate has a diameter between 5 mm and 20 mm. The membrane component comprises a membrane made from hydrophobic material.

A sealing plug arrangement for sealing a combined filling and degassing opening of an accumulator. The sealing plug arrangement includes at least one valve part, one valve holder, and one sealing plug. The valve part is arranged on the valve holder and forms an openable valve mechanism with the valve holder for sealing at least one interior space of the accumulator from the surrounding area upon pressurization. The sealing plug includes at least one fastening means for fixing to the filling and degassing opening and at the same time subjecting the valve part to a pretensioning force toward the valve holder. The valve holder includes at least one extension axially projecting toward the valve part which is formed as a circumferential sealing edge on a surface facing the valve part on which the valve part rests.

An air venting system for a constant velocity joint (20) having an inner race (24), an outer race (22), a cage (26), a plurality of torque transferring elements (28), a drive sleeve, a drive nut and a boot assembly. The outer race has a wall portion (90) having a vent hole (88, 242) with a first and a second axially extending channel (224, 264). A radially extending wall integrally connects the second axially extending channel to the first axially extending channel. A valve (256) having a stopper portion (264), a disk portion (258) and a breather portion (260) is at least partially located within the vent hole. The breather portion (260) further includes an axially extending ring (292) that terminates in a radially extending wall. At least a portion (300) of an edge portion of the radially extending wall of the breather portion of the valve is in direct contact with at least a portion (250) of an outer surface of the wall portion of the outer race.
