摘要： A spring-driven guided check valve which eliminates fluttering of the disc as it moves between the open and closed position against a seat. A disc has an integrated guide which slides against a sleeve inside the body of the valve. This configuration only allows linear movement of the seat in a direction towards (and away) from an inlet face without changing the orientation of the disc. The disc is held in a constant orientation and thus cannot shift at an inclined attitude (flutter). Thus, once the valve closes and the disc makes contact with the seat, the entire disc would contact the entire seat at the same point in time because of the parallel orientation of the disc to the contacting surface of the seat.

摘要： A valve device, comprising a valve tappet (18), which causes a controlled opening or blocking of a fluid flow channel (16) in an engagement position on a valve seat (22) and which can be brought from a starting position to the engagement position as a reaction to an application of pressure by means of a pressure fluid, wherein the pressure fluid is conveyed by electromagnetically driven pumping element (24) into a pressure chamber (44) associated with the valve tappet in such a way that the application of pressure for driving the valve tappet is accomplished by a plurality of pumping strokes of the pumping element, which has a conveying piston (26), in particular a reciprocating piston.

摘要： An overpressure or relief valve (30) for a buoyancy compensator device (10) for underwater use of the type comprising an expandable bag (12) internally provided with at least one air chamber is disclosed. The valve (30) comprising at least one mobile shutter element (32) configured to occlude at least one corresponding hole (62) formed on an abutment plate (46) that is configured to be applied on a wall of the air chamber. The mobile shutter element (32) being operatively connected to a first end of an elastic element (34), whereas a second end of said elastic element (34) is in turn operatively connected to an electric actuator element (36), actuated by an electrical current and configured to counteract, in certain operating conditions of the valve (30), the elastic force of the elastic element (34), so as to perform the selective opening and closing of the mobile shutter element (32) and, consequently, respectively allowing or preventing air from the hole (62), and then from the inside of the air chamber, from passing towards one or more through holes (58) formed on the outer body (60) of the valve (30) and vice versa.

摘要： An apparatus can include a housing, a plunger configured to reciprocate along an axis within the housing, and an internal fluid chamber disposed in the housing. A valve, having a valve base and a deformable seal, can also be included in the apparatus. The apparatus can further include a seat having an aperture therein. The valve is configured to move into and out of contact with the seat when the plunger reciprocates within the housing, based upon a fluid pressure in the internal flow chamber. In addition, an outer diameter of the deformable seal of the valve is less than an outer diameter of the seat.
