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： Provide is a relief valve in which the flexibility of an attaching position is higher than a conventional relief valve. In the relief valve of the present invention, a discharge hole for discharging a fluid is arranged on a side surface of a cylindrical portion which protrudes from an end surface of a head portion in a bolt-type valve body. A direction change member which changes a direction in which the discharge hole is open to an arbitrary direction is provided. In this way, the relief valve is attached to a fluid device, and then with the direction change member, it is possible to direct the fluid discharge direction to a desired direction, and accordingly, the flexibility of the attaching position of the relief valve is enhanced as compared with the conventional relief valve.

摘要： A switchable slot valve for a coating plant controls delivery of a pasty coating material. The switchable slot valve has a valve bore incorporated in a valve main body and is aligned in a valve extent direction, and a valve control rod is rotatable to switch between a throughput position and a closed position and is mounted in the valve bore by bearing faces is disposed. To mitigate disruptions by coating material which has made its way into a bearing gap between the valve bore and the bearing faces, depression regions are provided in the region of which the respective outer circumferential part-face does not bear on the inner circumferential face of the valve bore, on the outer circumferential part-faces between the slot-shaped duct inlet and the slot-shaped duct outlet.

摘要： A shut-off member of a pressure reducing valve of a pressure regulator device, such as a diaphragm-type first stage for scuba diving, includes an enlarged head connected to a shaft and cooperating with a valve seat that separates a chamber supplied with high pressure gas from a chamber in which gas is at a lower pressure. The enlarged head and an end section of predetermined length of the shaft, connected to the enlarged head, are seamlessly coated with at least one layer of elastomeric material. Such coating of elastomeric material is limited to an end portion of the shaft connected to the enlarged head and the coated shaft portion is entirely contained in the high-pressure chamber in any operating position of the shut-off member.

摘要： This valve is integrated into a fluid distribution network and enables selective interruption or authorization of the circulation of a fluid. The valve includes a fluid blocking member driven in rotation by an actuator device of the valve and at least one journal, a hollow body inside which the blocking member is mobile and which defines at least one bore for receiving the journal, and a bearing disposed around each journal and inside the bore of the body enabling support of the journal and guidance thereof in rotation relative to the bore, thereby centering the journal. The valve further includes a device for immobilizing and sealing for maintenance the journal relative to the body of the valve. This immobilization device is disposed on the same side of the bearing as the internal volume of the hollow body and is maneuverable via the bearing to go from a non-clamped first configuration to a clamped second configuration in which it immobilizes the journal in the bore and vice versa.
