    Abstract: A valve (500) comprising a member (514) subject to a first force operative to keep said value closed, said member being sensitive to an index pressure (P1); and an outlet (516) at a second pressure (P2), said index pressure (P1) providing a second force in opposition to said first force when a differential between said second pressure (P2) and said index pressure (P1) is provided to said member (514): and opening the valve when said second pressure (P2) is sufficiently less than the index pressure (P1) to overcome the first force, and a vent (520) operably associated with the member (514), said vent (520) opening when said valve is opened.

    Abstract: A flow control valve for medical liquid is disclosed. A plurality of flow restrictors (54 a - c) are located in the flow path to define a plurality of flow streams of differing flow rates. A flow control member (48) is disposed in the flow path, and has a plurality of discrete apertures in a first region or plane and at least one aperture in a second region or plane spaced apart from the first plane. The flow control member may be rotated between a first position in which one of the plurality of apertures in the first plane is in communication with one of the flow streams to define a first flow rate through the valve, and a second position in which one of the at least one aperture in the second plane is in communication with a different one of the flow streams to define a second flow rate through the valve different from the first flow rate.

    Abstract: A fluid flow rate switching device providing a plurality of precise user selectable flow rates. Generally, the device includes a housing having a port and a plurality of passages. Respectively disposed in each of the passages is a rigid capillary tube for regulating the flow rate of a therapeutic fluid through the passages. Further, a valve is rotatably connected to the housing for operably connecting and disconnecting the port from one or more of the passages.

    Abstract: A valve is disclosed for dispensing a flowable material. The valve has a first chamber (40) at a first pressure wherein said first chamber (40) defines an outlet (28) in communication with said first chamber (40). A second chamber (42) is at a second pressure. The valve has a stop (18) indexed against a third pressure, operating to selectively place the first chamber (40) into communication with the second chamber (42). The stop (18) is operative to connect the second chamber (42) to said first chamber (40) when the first pressure is less than the third pressure.
