    摘要: A device may be configured to deliver an agent to a target tissue via pressurized fluid and the device may include a catheter including a lumen; an enclosure configured to store an agent, receive a pressurized fluid, and release a combination of the pressurized fluid and the agent; and a valve downstream of the enclosure to receive the combination of the pressurized fluid and the agent from the enclosure. The valve may have a first configuration preventing flow of the combination through the lumen and a second configuration permitting flow of the combination through the lumen.

    摘要: A quarter-turn pin valve actuator has a housing and a rotatable core configured to rotate about a central axis inside the housing. The rotatable core has a two bearings mounted to roll in a circular path about the central axis. The actuator comprises a two-position ramped roller plate that is displaced axially when the bearings are rolled a quarter turn. The actuator includes a push plate and a spring disposed between the push plate and the ramped roller plate. The push plate has a central socket for receiving a pin of a pin valve to which the actuator is connected. When the rotatable core is rotated, the bearings exert a force via the ramped roller plate on the push plate which in turn displaces a pin of a pin valve to which the actuator is connected.

    摘要: Disclosed is a quarter-turn valve (1) comprising a valve housing (2) including a flow channel (21) through which a fluid flow may be guided. The quarter-turn valve (1) further comprises a blocking element (3) arranged to rotate between a first position, in which said blocking element (3) allows flow through the flow channel, and a second position in which the blocking element (3) blocks flow through the flow channel (21), and the valve comprises a stem (4) arranged to actuate the blocking element (3) through a gearing (5). The gearing (5) of the quarter turn valve (1) comprises a gear nut (6) arranged to engage the stem (4) so that when the stem (4) and the gear nut (6) are mutually rotated, the gear nut (6) is displaced along the longitudinal direction of the stem (4), and a gear sleeve (7) comprising a sleeve helical track (8), wherein the gear sleeve (7) is connected to the blocking element (3). The gearing (5) of thequarter turn valve (1) also comprises a gear housing (9) including a housing helical track (10), wherein the gear housing (9) is fixed in relation to the valve housing (2), and wherein the gear nut (6) is arranged to engage both the sleeve helical track (8) and the housing helical track (10).

    摘要: An internal valve (100) includes a valve stem (106) disposed in a valve body (110), a poppet valve (102) coupled to the stem, and a bleed valve (104) is coupled to the stem. The valve stem is shiftable from a first position in which the poppet valve and the bleed valve are closed, to a second position in which the bleed valve is open, and a third position in which the bleed valve is closed and the poppet valve is open, and poppet may shift closed in response to a pressure change. The valve body includes a shoulder arranged (318) for sealing engagement with a container flange (304) and is between an inlet and a flange of the valve body and spaced away from the inlet, the shoulder arranged on the valve body to place the inlet a desired distance away from the inner wall of the fluid container (131).
