A valve device increases or decreases a flow rate of EGR gas. The valve device includes a housing, a bypass valve body, an EGR valve body. The housing includes: a first upstream passage into which the EGR gas cooled by an EGR cooler flows; a second upstream passage into which the EGR gas that bypasses the EGR cooler flows; a junction connected to each of a gas-flow downstream of the first upstream passage and a gas-flow downstream of the second upstream passage; and a downstream passage connected to the first upstream passage and the second upstream passage via the junction. The bypass valve body is provided in the second upstream passage. The EGR valve body is provided in the downstream passage.

The housing includes a first upstream passage into which the EGR gas cooled by an EGR cooler flows, a second upstream passage into which the EGR gas that bypasses the EGR cooler flows, a junction connected to each of a gas-flow downstream side of the first upstream passage and a gas-flow downstream side of the second upstream passage, and a downstream passage connected to the first upstream passage and the second upstream passage via the junction. The bypass valve body opens and closes the second upstream passage. The EGR valve body is provided in the downstream passage, rotates around an EGR valve axis.

The present invention refers to a valve actuator device comprising an upper plate (1) and a lower plate (2) facing each other, defining a housing inside which a cylinder (3) with a stem is housed, said stem (5) being connected to a rotor arm (7) by means of a guiding element (8) inserted and slidably in line between a lower position and an upper position within guiding grooves (9, 9′) arranged in the respective upper plate (1) and lower plate (2), wherein said rotor arm (7) is configured to rotate about a rotation axle (11) arranged in a rotating element (12), said rotating element (12) being formed by two portions: an adapter portion (12′) for the connection thereof with the valve stem comprising the rotation axle (11) in which the rotor arm (7) is inserted, and a display portion (12″) comprising a visual indicator (17), and a position sensor system (18, 18′) for detecting an open position and a closed position.

A cap assembly includes two caps each pivotable about an axis of a respective pivot rod between an open position and a closed position, the two pivot rods arranged adjacent each other with parallel pivot axes (B) to define a hinge region, each cap having a pivot end extending into the hinge region between the two pivot rods; and a common pivot mechanism arranged to push against the pivot ends, in response to actuation of the pivot mechanism, to pivot the caps substantially simultaneously to the closed position, the common pivot mechanism comprising: a lever; a cam in connection with the lever and located in the hinge region such that actuation of the lever causes movement of the cam in the hinge region along the direction of the pivot axes; a plunger located in the hinge region between the cam and the pivot ends.

A valve component for a valve, the valve comprises a valve housing defining a hollow bore along which flowable material may flow. The valve component comprises a valve member movable between a valve open position for the valve member to open the hollow bore and a valve closed position for the valve member to close the hollow bore, and a valve control mechanism including a drive member configured to be operable to move the valve member between the valve open position and the valve closed position, the drive member operable to rotate the valve member between the valve open position and a valve intermediate position and to linearly move the valve member between the valve intermediate position and the valve closed position.

Apparatus and method of a valve assembly that may be integrated into an inflatable device. The valve assembly may include a valve that is rotatable within a housing. The valve may allow for one-way passage of air either into or out of the inflatable device depending on the configuration of the valve. The valve system may provide an easy way to both inflate and deflate an inflation device with minimal effort from a user.

A valve for use in a tank vessel that includes a valve housing configured to fit into a threaded vent opening of the tank vessel and a sleeve weldment coupled to the valve housing. The sleeve weldment includes a first end configured to protrude into an interior volume of the tank vessel, and the first end is thermally balanced with the interior volume of the tank vessel. The valve also includes a valve plunger configured to be installed within the sleeve weldment. The valve plunger includes a valve bottom configured to seal an opening between the valve bottom and an interior opening of the sleeve weldment. The valve also may include a cam configured to force the valve plunger into the interior of the tank vessel to break the seal between the valve bottom and the interior opening of the sleeve weldment.

Disclosed is a wafer processing system, a dual gate system, and methods for operating these systems. The dual gate system may have a shaft, a first gate and a second gate coupled to the shaft at opposite sides thereof, and an actuator coupled to the shaft. The actuator is configured to tilt together the shaft, the first gate, and the second gate to a first sealed gate position or to a second sealed gate position. The actuator can be operated using a pneumatic mechanism, an electro-magnetic mechanism, or a cam follower mechanism.

A pump includes a pair of valves, coupled to a camshaft that selectively opens and closes the valves such that when one valve opens the other valve closes. The valves are in fluid communication with a piston chamber. A crankshaft operates a piston in a piston cylinder with the opening and closing of the valves such that as the piston is drawn from the piston chamber, the inlet valve is open and the outlet valve is closed and when the piston is forced into the chamber, the outlet valve is open and the inlet valve is closed. The camshaft and crankshaft are coupled together to cause synchronous operation of the valves and piston.
