A container for heating and cooking food includes: a lower containment body; an upper cover hermetically coupling with the lower containment body; and an automatic valve, in the shape of a cap, integrated in the upper cover, allowing steam to vent. The automatic venting valve includes: a control member controlling the pressure inside the container; and an elastic tongue associated and moulded in one piece with the control member. The control member is housed and rotatable in a recess in the upper cover. The elastic tongue has a deformed configuration, applying an elastic force pressing and closing the control member against a through hole in the bottom of the recess housing the control member, preventing the steam from exiting the container. When the steam pressure reaches a critical value, the control member rotates and tilts, removing the control member from the through hole, allowing the steam to vent.

A sprinkler configured for engagement with a coupling, the sprinkler includes a raised lip end, the sprinkler defining a raised lip at the raised lip end; and a deflector end disposed opposite from the raised lip end, the sprinkler defining a groove between the raised lip and the deflector end.

A valve for a bypass conduit is comprised of a rigid inner frame having an arm with a tab at one end and a hinge at an opposite end. A flexible outer seal is positioned over the inner frame, the flexible outer seal defining a peripheral edge to substantially house the tab and arm of the inner frame. The valve is pivotable from a first position to a second position on the bypass conduit.

A backflow prevention device includes a main pipe body extending along a first center longitudinal axis, at least one check valve disposed within the main pipe body, an inlet pipe connected to an inlet side of the main pipe body, and an outlet pipe connected to an outlet side of the main pipe body. The inlet pipe and the outlet pipe extend along a second center longitudinal axis. The first center longitudinal axis is offset with respect to the second center longitudinal axis in a direction perpendicular to the first and second center longitudinal axes. A center of the valve seat of the at least one check valve is offset with respect to the second center longitudinal axis in the direction perpendicular to the first and second longitudinal axes.

A backflow prevention assembly includes a body forming two buckets, wherein flow passes through the body from an inlet to an outlet along an axis and consecutively through each of the buckets. A single zone test cover encloses a first of the buckets to form a single zone chamber. A dual zone test cover encloses a second of the buckets with a dual zone cartridge assembly therein. The dual zone test cover has two test cocks. The dual zone cartridge assembly includes a frame having a valve seat, wherein the frame includes a lumen providing fluid communication from a dual zone chamber upstream of the valve seat to a first of the two test cocks of the dual zone test cover, and wherein the second of the two test cocks of the dual zone test cover is in fluid communication with the dual zone chamber downstream of the valve seat.

A valve assembly for an exhaust system of a vehicle comprises a housing defining an inlet, an outlet, and a longitudinally extending exhaust gas passageway in fluid communication with the inlet and the outlet. The valve assembly further comprises a valve flap disposed in the housing and rotatable between a first position restricting exhaust gas flow through the exhaust gas passageway, and a second position whereat exhaust gas flow through the exhaust gas passageway is less restricted. A mass damper is disposed within the exhaust gas passageway and attached to the valve flap. The mass damper includes end portions and an intermediate portion disposed between the end portions with the intermediate portion having a thickness that is greater than a thickness of the end portions. The mass damper is positioned proximate an inner surface of the housing and positioned between the valve flap and the housing when the valve flap is at the second position.

An oven includes a cooking chamber, a cabinet at least partially surrounding the cooking chamber, and a water reservoir having a reservoir inlet and a reservoir outlet. The oven further includes a water fill assembly including an opening, a water-receiving cavity and a fill outlet from the water-receiving cavity, the water fill assembly defining a fluid flow path in from the opening and out through the fill outlet, a check valve in fluid communication with the fill outlet downstream of the fluid flow path defined by the water fill assembly, the check valve configured in a closed state under a force of gravity on at least a portion thereof and opening by a flow force of fluid out of the fill outlet and through the check valve, and a conduit connecting the check valve with the water reservoir inlet downstream of the fill outlet.
