A gas grill is disclosed having a gas control valve with a push to sear feature. The gas control valve has a housing with a valve core rotatably disposed within the housing. A sear valve is disposed within the valve core. A user rotates the valve core within the housing to selectively align a gas inlet port with an inlet passage and to align a sear gas port and a sear gas flow passage. The sear valve has a sear valve element which is selectively movable relative to the valve core to selectively pass a sear gas through a sear gas port and a sear flow passage to the forward end of the valve housing, and then to the grill. A bias member, preferably a coil spring, is mounted between the sear valve element and the valve core for urging the sear valve element to a closed position.

A valve may include a housing forming one inlet and at least one outlet, an operating unit mounted in the housing, and performing expansion or contraction in accordance with a temperature of a flowing working fluid to selectively connect the at least outlet with the one inlet for exhausting the flowing working fluid outside of the housing, wherein the operating unit includes a sliding member slidably inserted into the interior of the housing, a flange member forming a penetration hole and fixedly mounted inside of the sliding member, a rod movably inserted into the penetration hole of the flange member, and a deformable member fixed at the penetration hole of the flange member and expanded or contracted in accordance with a temperature of the flowing working fluid.

An example shuttle valve includes: (i) a valve body comprising a longitudinal cylindrical bore, a first inlet port, a second inlet port, an outlet port, and a key that protrudes radially inward within the longitudinal cylindrical bore; and (ii) a shuttle mounted in the longitudinal cylindrical bore and configured to move axially therein, wherein the shuttle comprises a plurality of radial protrusions that protrude radially outward from, and are circumferentially spaced apart about, a peripheral surface of the shuttle, and wherein the key of the valve body is interposed between two radial protrusions of the plurality of radial protrusions.

A valve apparatus having a co-axial fluid inlet and outlet is disclosed. The valve apparatus comprises a housing having a generally tapering main cavity. The valve apparatus further comprises a first fluid inlet formed therein for receiving fluid from a source, a first fluid outlet for returning the fluid to the source, a second fluid outlet for discharging fluid from the housing and a second fluid inlet for receiving fluid and returning the fluid to the fluid source. A valve mechanism is slidingly mounted within a first valve chamber for controlling flow from the first fluid inlet to the second fluid outlet, the valve mechanism having a first position wherein a second valve chamber is in communication with the first valve chamber and the first fluid outlet, and a second position wherein a third valve chamber is in fluid communication with the first valve chamber and the second fluid outlet.

A hydraulic cartridge valve includes a sleeve with a longitudinal bore that forms a working port via an end opening. A plunger is accommodated for linear motion in the longitudinal bore. The sleeve is penetrated in an inlet port region by a first radial bore that extends radially with respect to a longitudinal axis of the hydraulic cartridge valve. The sleeve is penetrated in a return port region by a second radial bore that extends radially with respect to the longitudinal axis. A first fluid flow path extends from the inlet port to the working port and a second fluid flow path extends from the working port to the return port. The plunger has third and fourth radial bores that extend radially with respect to the longitudinal axis and form part of the first and second fluid flow paths, respectively.

An internal combustion engine has first and second combustion chambers, first and second exhaust gas line elements, and an exhaust gas turbocharger which has a first flood, a second flood, and a third flood. A bypass device has a bypass line that can be flowed through by exhaust gas from the first and second exhaust gas line elements and via the bypass line a turbine wheel is bypassed by a first part of the exhaust gas from the first and second exhaust gas line elements. A valve device includes a first valve element, via which an amount of the exhaust gas flowing through the bypass line and bypassing the turbine wheel from the first and second exhaust gas line elements is settable. A third exhaust gas line element opens out into the third flood.
