摘要： A flow control device includes a stack of annular discs positioned in a flow path. Each disc includes fluid passageways extending between inner and outer perimeters of the disc, with each passageway defining a flow axis extending out of the disc and radially offset from a central axis of the discs. A plug is moveable relative to the discs between closed and open positions. In the closed position, a cylindrical section of the plug is positioned to block fluid flow through the annular discs. In the open position, the annular discs and a tapered section of the plug collectively define an annular vortex chamber. The fluid passageways in the annular discs and the tapered section of the plug collectively impart a rotational flow when the plug is in the open position and as fluid exits the annular discs.

摘要： A check valve for a spray nozzle including a tubular valve body, a shut-off member and a valve seat, wherein the shut-off member is mounted for movement at least in a longitudinal direction of the tubular valve body. The shut-off member is connected to the valve body by a corrugated tube disposed parallel to the longitudinal direction, wherein the shut-off member is biased toward the valve seat due to the spring effect of the corrugated tube. The check valve is suitable for use in, for example, descaling nozzles.

摘要： A check valve (32) includes a cylindrical body (32) and a valve plate (32) attached to one end of the body (32) to open and close a flow outlet. A stepped seat element (36a) having a seat surface (36a) is formed along the periphery of the flow outlet of the body (40). The valve plate (40) is press-cut from a thin stainless steel plate to be integrally formed as a leaf spring. The valve plate includes a leaf element movable with respect to the seat surface so as to close and open the flow outlet, an arm element (41) coupled to the leaf element (41) via a joint element, and a base element connected to the arm element and received by a valve support projection on the cylindrical body.

摘要： A check valve assembly is disposed in a flow path of a high pressure hydraulic actuating system between a source of pressurized fluid and a pressure responsive mechanism to limit flow to a single direction therebetween. A valve housing defines a fluid passage therethrough with a first axis therealong. The fluid passage has an annular first seat surface normal to the axis. A fitting is fixed to the valve housing and has a post directed toward fluid flow from the source of pressurized fluid. A check valve assembly slidably translates on the post between a closed position abutting the first seat surface which restricts flow toward the pressure source, and an open position spaced from the first seat surface which permits flow toward the pressure responsive mechanism. A spring disposed between the fitting and the check biases the check to the closed position.

摘要： A one-way valve for dispensing fluid assures, after the fluid has been dispensed, that any flow of contaminants into the source of the fluid is prevented. The one-way valve has a disc shaped valve body enclosed about the circumferential edge by an elastomeric membrane. Separate passageways conduct the fluid through the valve body with the fluid flowing from one passageway to the other between the circumferential edge and the elastomeric membrane. The valve body has a greater diameter than axial length.
