In order to provide a pressure equalization apparatus (10) by means of which a pressure equalization can be brought about in the event of an overpressure—in particular, in an electrochemical system—and which is as simple as possible to produce, according to the invention, the pressure equalization apparatus comprises a main element (110), a sealing device (112), and a connection device (114) for connecting the main element and the sealing device, wherein the sealing device sealingly bears against the main element when the pressure equalization apparatus is in a closed state and is fixed relative to the main element by means of the connection device, and wherein a fixing connection between the main element and the sealing device which is formed thereby can be released in order to unblock a fluid connection between the interior of the pressure equalization apparatus and surroundings of the pressure equalization apparatus, and wherein the connection device comprises a spring element (150), the spring force of which acts in particular in a direction extending crosswise to an opening direction of the pressure equalization apparatus.

A thin gas transportation device includes an inlet plate, a resonance sheet, an actuating element, a first insulation frame attached to the actuating element, a conductive frame, and a second insulation frame attached to the conductive frame. The conductive frame has a conductive outer frame attached to the first insulation frame, an elastic conductive pin, and a conductive piece connected to an outer edge portion of the conductive outer frame. One end of the elastic conductive pin is connected to an inner edge portion of the conductive outer frame, and the other end of the elastic conductive pin extends obliquely toward the actuating element and forms a bent portion. The bent portion presses against the actuating element and is electrically connected to the actuating element, and the bent portion is strip-shaped.

A pressure relief valve may comprise a housing, a disk, and a seal. The disk may be configured to deflect relative to the housing. The seal may form a sealing interface with at least one of the housing or disk. The pressure relief valve may be coupled to an inflatable slide or an aspirator.

According to embodiments, a pressure relief mechanism comprises a case with an installation hole formed therein, and a pressure relief valve. The pressure relief valve comprises an insertion portion which comprising a vent path formed in an axial portion of the insertion portion and a slit formed in a peripheral wall portion of the insertion portion so as to communicate with the vent path, a pedestal portion provided at an outer end of the insertion portion, a locking portion provided at an inner end of the insertion portion and locked on an inner edge of the installation hole, and a ring-like seal member interposed between around the installation hole and the pedestal portion, the seal portion comprising an elastic member.

A system for detecting safe operating conditions and maintained integrity in a Pressure Safety Valve (PSV) the valve comprising an inlet, an outlet, a valve disc controlling fluid flow between the inlet and outlet, a stem connected to the valve disc, a spring washer, and a spring in communication with the valve disc and the spring washer, a vibration sensor which detects vibration in the valve disc, an inlet pressure sensor which detects the static pressure in the inlet, a position sensor which detects the position of the valve disc transferred through the stem, a compression load cell sensor which detects the dynamic force applied on the valve spring washer by the spring, an outlet pressure sensor which detects the pressure in the outlet, a separate shock sensor adapted to determine if the PSV has popped and then activate a microcontroller.

A pressure relief cover for reducing pressure generated in a cell-like cavity, such as a battery cell, having a cover part which holds a seal for sealing a housing opening up to a predetermined cell pressure and having a holding device to fasten it to the housing opening. An advantageous type of mounting with a reliable function is achieved in that the holding device has a spring clip attached to the underside of the cover part at the housing opening with a plurality of radially outwardly directed spring tongues which at their ends are provided with spring sections which are resiliently movable backward in the radial direction upon pressing the cover part onto the housing opening through the opening edge and snap back under a wall area around the opening edge after penetrating the housing opening.

A battery pack includes: a battery cell; a pack case that accommodates the battery cell and that is provided with an opening; and a valve structure provided to open and close the opening. The valve structure includes a valve member having a valve body portion fitted to an inner peripheral surface of the opening, and a biasing member provided inside the pack case. When an internal pressure of the pack case is increased, the valve member is moved to an outer side of the pack case so as to form a clearance between an outer peripheral surface of the valve body portion and the inner peripheral surface of the opening, and the biasing member biases the valve member toward an inner side of the pack case.
