An exhaust-gas flap device, especially for the exhaust-gas flow of an internal combustion engine, has a flap pipe and a flap plate that is supported, in the interior of the flap pipe, on a pivot shaft that is rotatable about a pivot axis. The exhaust-gas flap device further includes a pivoting drive for the pivot shaft with a drive element. A coupling unit couples the drive element to the pivot shaft for conjoint rotation about the pivot axis. Vibration-damping material is arranged in the region of the coupling unit.

A folding hanger includes a hook extending from an upper end of a hinge pin for suspending the pin. First and second hanger arms each have proximal and distal ends and define a support surface therebetween. Each proximal end has a stop. A knuckle having a hole extends from each proximal end. The pin passes through the holes along an axis, coupling the arms and hook whereby the arms are movable between extended and folded configurations. The stops abut when the arms are extended, and are separated when folded. The hanger has a center of gravity when the arms are extended and suspended by the hook such that the axis is angled relative to vertical in a first direction and the stops bias abutting. The arms each have a center of gravity such that angular movement of the axis past an unstable equilibrium causes the arms to move toward folded.

The present disclosure in at least one embodiment provides a solenoid valve for a vehicle brake, including a sleeve internally formed with a hollow interior space and fixed to a pump housing, a coil surrounding the sleeve, a first magnetic body at least partially accommodated in the hollow interior space of the sleeve, a second magnetic body at least partially accommodated in the hollow interior space of the sleeve, an elastic member disposed between the first magnetic body and the second magnetic body, an orifice configured to open and close as the second magnetic body moves, and a damping member disposed between the first magnetic body and the second magnetic body to form a gap between the first magnetic body and the second magnetic body.

A damping valve having a damping valve body with at least one flow channel for damping medium. A valve rod is arranged in the flow channel. The valve rod cooperates with a valve disk and a valve seat surface. The valve rod carries a further valve disk that cooperates with a second valve seat surface. The first valve disk together with the first valve seat surface forms a first partial valve having a first permanently open pilot orifice cross section, and the second valve disk together with the second valve seat surface forms a second partial valve having a second pilot orifice cross section, and a shuttle valve is formed which opens one partial valve and closes the other partial valve depending on the flow direction.

Seat valve, with a valve body having a plurality of inlet channels, with a plurality of closing elements arranged movably in a longitudinal direction L, each inlet channel being assigned a closing element for opening and closing the inlet channel, with a closing spring assigned to each closing element. The closing spring applies a prestressing force to the respective closing element to close the inlet channel. Each closing element assigned a braking device which is arranged separately from the closing element and which gradually brakes an opening movement of the closing element when the inlet channel is opened, independently of the closing spring. The braking device having a stop body with a stop surface against which the closing element can be brought to bear after an opening movement when the inlet channel is opened, the stop body being arranged movably and/or yieldingly in the opening direction of the closing element.

A plate armature damping device for a tilting armature valve includes at least one damping body which can be fixed to a plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element. The at least one damping body has a geometric contour including at least one bulge on a surface of the at least one damping body facing the counter-element, which is configured such that, on the impact movement of the plate armature, the volume of the at least one damping body contributing to the damping increases.

A fuel tank isolation solenoid valve for a vehicle includes: a plunger disposed in the isolation solenoid valve to be vertically moved and has first vent holes for releasing overpressure or over-negative pressure; a valve body disposed in the isolation solenoid valve to be vertically moved and has second vent holes for releasing overpressure or over-negative pressure.

Embodiments of a valve assembly and a plumbing system incorporating the same are provided herein. In some embodiments, a valve assembly for use with an enclosed environment includes a housing having an interior volume, an inlet disposed at a first end of the housing and fluidly coupled to an environment surrounding the housing, and an outlet disposed at a second end of the housing opposite the first end and fluidly coupled to the enclosed environment; a first valve having a first valve seat and a first sealing member at least partially extending through a first opening in the first valve seat in a closed position; and a second valve disposed beneath the first valve and having a second valve seat and a second sealing member at least partially extending through a second opening in the second valve seat in a closed position.
