Abstract
Abstract A valve which is particularly adapted to be inserted in a predetermined flow line arrangement in angiography procedures. The valve includes an inner member having at least one axial bore and at least one annular groove communicating with each bore. At least one sealing ring is exteriorly mounted on the inner member to isolate the grooves. An outer member having a radially extending outlet is mounted on the inner member so as to be rotatably and reciprocally movable with respect thereto so as to selectively place the outlet in communication with one of the grooves and point it in any desired direction.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
A valve adapted to be inserted in a predetermined flow line arrangement and designed to withstand high flow pressures comprising; an inner member having at least one axial bore and at least one inner annular groove communicating with each bore, sealing rings exteriorly mounted on the inner member to isolate the grooves, an outer member having a hollow radial extention for fluid flow therethrough and being mounted on the inner member so as to be rotatably and reciprocally movable with respect thereto so as to selectively place the outlet in communication with one of the grooves and pointed in any desired direction, the inner member being cylindrical in configuration and having an annular outer surface, each sealing ring being an 0-ring externally mounted on the outer surface of the inner member, the outer member having an annular inner surface corresponding to the annular outer surface of the inner member and to engage in sealing relationship with respect to the sealing rings, the outer member being freely rotatable 360* about the inner member in sealed relationship with respect to the 0-rings about the entire rotational path, and the inner and outer members being transparent to facilitate observation of the flow paths therethrough.
Claim 2
Dependent Claim
201 words
A valve adapted to be inserted in a predetermined flow line arrangement and designed to withstand high flow pressures comprising; an inner member having at least one axial bore and at least one inner annular groove communicating with each bore, sealing rings exteriorly mounted on the inner member to isolate the grooves, an outer member having a hollow radial extention for fluid flow therethrough and being mounted on the inner member so as to be rotatably and reciprocally movable with respect thereto so as to selectively place the outlet in communication with one of the grooves and pointed in any desired direction, the inner member being cylindrical in configuration and having an annular outer surface, each sealing ring being an 0-ring externally mounted on the outer surface of the inner member, the outer member having an annular inner surface corresponding to the annular outer surface of the inner member and to engage in sealing relationship with respect to the sealing rings, the outer member being freely rotatable 360* about the inner member in sealed relationship with respect to the 0-rings about the entire rotational path, and the inner and outer members being transparent to facilitate observation of the flow paths therethrough.
Claim 3
Dependent Claim
56 words
The invention in accordance with claim 1 wherein the outer member is shorter than said inner member and stop means are provided on the outer surface of said inner member to engage with the edges of said outer member and to define a predetermined travel path of said outer member with respect to said inner member.
Claim 4
Dependent Claim
108 words
The invention in accordance with claim 1 wherein there are three spaced sealing rings on said inner member, the outer annular groove on said inner member being positioned between the first and second sealing members, the radially extending outlet in said outer member being positioned so that when said outer member is in one position the radially extending outlet is between said first and second sealing rings and in communication with the groove in the inner member and when said outer member is shifted to a predetermined position said radially extending outlet is positioned between said second and third groove and sealed from communication with said annular groove.
Claim 5
Dependent Claim
118 words
The invention in accordance with claim 1 wherein said inner member has a pair of spaced annular grooves on the outer surface thereof, three spaced sealing rings are mounted on the inner member with one of the annular grooves positioned between the first and second sealing ring and the other of the annular grooves positioned between the second and third sealing rings, the radially extending outlet in the outer member being positioned so that when the outer member is in a first position the outlet will be in alignment with the one of said grooves and when the outer member is shifted to a second position the outlet will be in communication with the other of said grooves.
Claim 6
Dependent Claim
129 words
The invention in accordance with claim 1 wherein there are three spaced sealing rings on said inner member, the outer annular groove on said inner member being positioned between the first and second sealing members, the radially extending outlet in said outer member being positioned so that when said outer member is in one position the radially extending outlet is between said first and second sealing rings and in communication with the groove in the inner member and when saiD outer member is shifted to a predetermined position said radially extending outlet is positioned between said second and third groove and sealed from communication with said annular groove, the axial bore of said inner member extending from one open end and terminating intermediate the ends of the inner member.
Claim 7
Dependent Claim
67 words
The invention in accordance with claim 3 wherein a cap having an inwardly extending prong is mounted on one end of said inner member in threaded interengagement therewith and a bushing is in the bore so that when the cap is threaded on the inner member, the prong willl compress the bushing and the axial bore of said inner member will be sealed at said one end.
