1. A fluid valve comprising:
- a fluid conduit having a first end and a second end;
a baffle within the conduit between the first and second ends having a first face oriented towards the first conduit end and a second face oriented towards the second conduit end;
a baffle seat within the conduit between the baffle and the second conduit end arranged so that when the second baffle face rests against the seat, fluid flow from the first conduit end to the second conduit end through the conduit is substantially blocked; and
an operating element between the baffle and the second conduit end having a baffle end within the conduit and an operating end, the baffle end of the operating element being movable relative to the baffle and operative for separating the baffle from the baffle seat.

Abstract
A valve for fluids with a fluid conduit having a first and a second end. A baffle within the conduit has a first face oriented towards the first conduit end and a second face oriented towards the second conduit end. A baffle seat within the conduit between the baffle and the second end is arranged so that when the second baffle face rests against the seat fluid flow through the conduit is substantially blocked. An operating element, preferably a rod, is moveable relative to but capable of bearing against the baffle to separate the baffle from the baffle seat.

28. A fluid valve comprising:
-
a first fluid conduit having a first opening; a second fluid conduit having a second opening, the first and second conduits being pivotably connected together at a mutual pivot point; a flexible tube interconnecting the first and second conduits, the flexible tube together with the first and second conduits, defining a fluid passageway between the first opening and the second opening; a baffle within the first conduit for varying the amount of fluid flow through the fluid passageway; an operating element, extending through the flexible element and in communication with the baffle and the second conduit, pivoting of the first and second conduits with respect to each other, causing the flexible tube to bend and the operating rod to move the baffle thereby varying the amount of fluid flow through the fluid passageway. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)

36. A fluid valve comprising:
-
a first fluid conduit; a second fluid conduit; a fluid passageway through the first and second conduits having a central axis; a mutual pivot point, offset from said axis, at which the first and second fluid conduits are pivotably connected to each other; a baffle within the fluid passageway in the first fluid conduit for varying the amount of fluid flow through the passageway; and an operating element in communication between the second conduit and the baffle so that pivoting of the conduits with respect to each other moves the baffle so as to vary the amount of fluid flow through the passageway. - View Dependent Claims (37, 38, 39, 40, 41)

42. A fluid valve comprising:
-
a first fluid conduit; a second fluid conduit sealedly connected to the first fluid conduit; a passageway through the first and second fluid conduits; a baffle within the fluid passageway of the first fluid conduit for varying the amount of fluid flow through the passageway; an operating rod in communication between the baffle and the second fluid conduit; and a mutual pivot point offset from the operating rod at which the fluid conduits are pivotally connected to each other, pivoting of the conduits causing the operating rod to move the baffle so as to vary the amount of fluid flow through the passageway. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50)

51. A fluid valve comprising:
-
an inlet section having an inlet connection to a source of fluid under pressure; an outlet section having an outlet; a fluid passageway through the inlet and outlet sections from the inlet to the outlet through the sealed connection; the inlet and outlet sections being pivotable towards and away from each other; a slidable and sealed connection along the passageway between the inlet and outlet sections; a baffle chamber having a baffle seat disposed within the fluid passageway of the inlet section; a baffle within the baffle chamber biased towards the seat by the fluid pressure, the baffle substantially blocking fluid flow when resting against the seat but allowing fluid flow when moved away from the seat; and an operating element in communication with the outlet section and with the baffle so that when the inlet and outlet sections are moved towards each other the operating element is moved and separates the baffle from the seat. - View Dependent Claims (52, 53, 54, 55, 56)
