Abstract: A fuel vapor switching and venting valve for an internal combustion engine. The fuel vapor switching and venting valve includes an electromagnet with an armature, a first connection, a second connection, a first valve seat which is arranged between the first connection and the second connection, a spring, a flow limiting element, a second valve seat which is arranged on the flow limiting element, and a valve body coupled to the armature of the electromagnet. The valve body has a first contact surface with which the valve body can be lowered onto and lifted off of the first valve seat, and a second contact surface with which the valve body can be moved against the second valve seat. The second valve seat is axially displaceable. The spring loads the second valve seat in a direction of the valve body.

Abstract: A beverage dispensing valve includes a housing defining a chamber with an inlet for receiving a fluid and an outlet for dispensing the fluid. A piston is located in the chamber and subjected to a fluid pressure exerted by the fluid received via the inlet. The piston is moved axially in the chamber by the fluid pressure such that the piston determines a flow characteristic of the fluid dispensed via the outlet. A plunger is received in the chamber, and the fluid pressure tends to move the piston towards the plunger. A spring tends to move the piston away from the plunger, against the fluid pressure. The plunger is axially registered in the chamber in discrete plunger positions, and each plunger position sets a discrete limit on axial movement of the piston thereby determining a predetermined flow characteristic of the fluid dispensed via the outlet.

Abstract: A hydraulic valve includes a sliding control member that delimits at least one constantly adjustable diaphragm. The sliding control member is configured to be moved in the direction of a longitudinal axis. The hydraulic valve further includes a locking device with a locking member that is configured to be moved counter to the force of a first spring transversely relative to the longitudinal axis. The hydraulic valve further includes at least one catch contour in which the locking member is configured to be engaged in such a positive-locking manner that the sliding control member is releasably retained in a catch position that is associated with the respective catch contour. The position of at least one catch contour is constantly adjustable in such a manner that the free cross-sectional surface-area of the at least one diaphragm is constantly adjustable in the associated catch position.

Abstract: Provided is a fluid controller in which reduction of the accuracy caused by the loosening of a screw portion and reduction of the durability caused by torsional stress are prevented. A stem vertical-movement-amount adjustment means 11 is provided with: a handle 41 which has a female screw 41b on an inner periphery thereof and which is rotatably supported by a casing 4; a movable body 42 in which a male screw 46b is provided on an outer periphery thereof and is screwed into the inner periphery of the handle 41; and a guide means 43 which prevents rotation of the movable body 42 relative to the casing 4 and which enables vertical movement of the movable body 42.

Abstract: A female screw member includes a female screw part with a female screw, and a projection part projecting in the direction of a center shaft of the female screw and having a working face in the rotating direction centering on the center shaft. The female screw part and projection part are integrally molded with a resin. The projection part has a spiral inclination face spirally inclining by one round from the working face centering on the center shaft of the female screw. The height H of the working face is equal to or smaller than a pitch P of the female screw. Using the projection part as a fully opening fixing stopper, a motor operated valve includes a valve main body having a valve seat, the female screw member attached to the valve main body, a motor having a rotator and stator, and a valve shaft. The valve shaft is screwed to a female screw of the female screw member, and is rotated and driven by the rotor, and has a fully opening movable stopper capable of contacting the fully opening fixing stopper.

Abstract: A poppet valve for controlling water flow is provided, the poppet valve includes a housing, a movable armature arranged within the housing, a pilot pin having first and second ends, and a return element associated with the pilot pin. The first end of the pilot pin is associated with and driven by the armature, and a poppet is arranged around the second end of the pilot pin. A cage is arranged around the poppet, the cage having a transverse opening adapted for water to flow therethrough. The armature is selectively actuated to drive the pilot pin in a first direction towards a closed position, in which the transverse opening of the cage is blocked by the poppet. The return element drives the pilot pin in a second direction towards an open position, in which the transverse opening of the cage is unblocked by the poppet.
