Abstract
Abstract A fluid flow control valve of the kind having a single port which is to be connected selectively to one or other of a pair of ports, said valve comprising a ported member connected to said single port by a flexible duct, said member being movable between two positions thus to be aligned with one or other of said pair of ports, means being provided for effecting automatically a seal between said member and a respective one of said ports when said alignment takes place, said member being movable preferably linearly across a surface containing said pair of ports, and said sealing means is arranged to force the member against said surface as it approaches alignment with said port.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
110 words
A fluid flow control valve of the kind having a single port which is to be connected selectively to one or other of a pair of ports, said valve comprising a ported member connected to said single port by a flexible duct, means for moving said member between two positions wherein it is aligned with one or other of said pair of ports, and cam means automatically actuated when alignment takes place for exerting a positive force on said ported member in the direction of the respective one of said ports with which it is aligned for effecting a seal between said member and said respective one of said ports.
Claim 2
Dependent Claim
110 words
A fluid flow control valve of the kind having a single port which is to be connected selectively to one or other of a pair of ports, said valve comprising a ported member connected to said single port by a flexible duct, means for moving said member between two positions wherein it is aligned with one or other of said pair of ports, and cam means automatically actuated when alignment takes place for exerting a positive force on said ported member in the direction of the respective one of said ports with which it is aligned for effecting a seal between said member and said respective one of said ports.
Claim 3
Dependent Claim
34 words
A fluid flow control valve according to claim 1, wherein said seal effecting means comprises a pair of ramps disposed one adjacent each of said pair of ports and engageable by said ported member.
Claim 4
Dependent Claim
38 words
A fluid flow control valve according to claim 2, wherein said ported member includes a roller adapted to engage one of said ramps as said member approaches a position of alignment with the associated one of said ports.
Claim 5
Dependent Claim
41 words
A fluid flow control valve according to claim 1, wherein said single port and said pair of ports are arranged in one or more walls of a housing surrounding same, within which said ported member and said flexible duct are disposed.
Claim 6
Dependent Claim
86 words
A fluid flow control valve according to claim 4, wherein said housing comprises a pair of end walls, and side walls, one of said end walls containing said single port, the other containing said pair of ports, said flexible duct being connected to one end to said single port and extending along and within said housing, said ported member being connected to the oTher end of said duct and movable linearly across said other end wall between two positions aligned respectively within said pair of ports.
Claim 7
Dependent Claim
36 words
The valve defined in claim 1 wherein said ported member is mounted on an end of said flexible tube and said seal effecting means comprises cam means operatively engaged by said member when alignment takes place.
Claim 8
Dependent Claim
38 words
The valve defined in claim 6, wherein said cam means comprises a stationary inclined face and a follower roller on said member is adapted to engage and move along said face as said member moves into alignment position.
Claim 9
Dependent Claim
22 words
The valve defined in claim 7 wherein means is provided for adjusting the cam means to vary the inclination of said face.
Claim 10
Dependent Claim
34 words
The valve defined in claim 1 wherein said pair of ports are contained in means providing a substantially continuous surface, and said ported member is slidable along said surface during movement between said positions.
Claim 11
Dependent Claim
37 words
A fluid flow control valve according to claim 9, wherein said ported member is provided with a sealing surface on one face thereof adapted to seal against a surface portion surrounding each of said pair of ports.
Claim 12
Dependent Claim
32 words
The valve defined in claim 9 wherein said surface is substantially flat and a fluid pressure motor is connected to move said ported member linearly along said surface between said alignment positions.
Claim 13
Dependent Claim
117 words
A fluid flow control valve of the kind having a single port which is to be connected selectively to one or other of a pair of ports, said valve comprising a ported member connected to said single port by a flexible duct, said member being movable between two positions thus to be aligned with one or other of said pair of ports, and means for effecting automatically and maintaining a seal between said member and a respective one of said ports when said alignment takes place, said seal effecting means comprising a pair of oppositely inclined ramps disposed one adjacent each of said pair of ports and engageable by said ported member in the respective alignment positions.
Claim 14
Dependent Claim
117 words
A fluid flow control valve of the kind having a single port which is to be connected selectively to one or other of a pair of ports, said valve comprising a ported member connected to said single port by a flexible duct, said member being movable between two positions thus to be aligned with one or other of said pair of ports, and means for effecting automatically and maintaining a seal between said member and a respective one of said ports when said alignment takes place, said seal effecting means comprising a pair of oppositely inclined ramps disposed one adjacent each of said pair of ports and engageable by said ported member in the respective alignment positions.
Claim 15
Dependent Claim
42 words
The fluid flow valve defined in claim 12 wherein each said ramp comprises an arm pivotally mounted at one end and having a permitted degree of pivotable movement which is adjustable thus to effect proper alignment and sealing of said ported member.
Claim 16
Dependent Claim
148 words
A fluid flow control valve of the kind having a single port which is to be connected selectively to one or other of a pair of ports, said valve comprising a ported member connected to said single port by a flexible duct, said member being movable between two positions thus to be aligned with one or other of said pair of ports, means being provided for effecting automatically a seal between said member and a respective one of said ports when said alignment takes place, said ported member being slidably movable across a surface containing said pair of ports and said sealing means being arranged to force said member against said surface when said alignment takes place, and said sealing means comprising a pair of oppositely inclined ramps disposed one adjacent each of said pair of ports and engageable by said ported member in the respective alignment positions.
Claim 17
Dependent Claim
148 words
