Abstract
Abstract In a restrictor valve, having a flow passage, a pair of aligned orifice plates are positioned in the housing to define an intermediate portion of the flow passage. A central disk, interposed between the pair of plates, is provided with an opening mating and mismating with the flow passage upon axial rotation of the disk. Externally operated gear means, extending through the housing, engages the periphery of the disk for axial rotation of the latter.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
193 words
A restrictor valve, comprising: a valve body having a flow passageway including an inlet leading to said passageway and an outlet leading from said passageway, said body having counterbores intersecting and spanning the passageway; a pair of stationary plates disposed within the counterbores in parallel spaced-apart relation, each of said plate having an orifice coaxially aligned with the passageway; a rotatable disk interposed between said plates, said disk having an orifice movable into and out of registration with the orifices of said plates for controlling the flow of fluid through the passageway said rotatable disk having end faces respectively contiguously contacting the respective said plate, each said end face having a flow-restricting inclined groove having a length at least equal to the diameter of the disk orifice formed therein communicating, at one end, with the orifice in said disk and terminating, at its other end, in the plane of the respective end face for changing the direction of a stream moving through the passageway when said rotatable disk orifice is out of registration with the orifices in said plates; and, means extending into said body and engaging said disk for rotating the latter.
Claim 2
Dependent Claim
193 words
A restrictor valve, comprising: a valve body having a flow passageway including an inlet leading to said passageway and an outlet leading from said passageway, said body having counterbores intersecting and spanning the passageway; a pair of stationary plates disposed within the counterbores in parallel spaced-apart relation, each of said plate having an orifice coaxially aligned with the passageway; a rotatable disk interposed between said plates, said disk having an orifice movable into and out of registration with the orifices of said plates for controlling the flow of fluid through the passageway said rotatable disk having end faces respectively contiguously contacting the respective said plate, each said end face having a flow-restricting inclined groove having a length at least equal to the diameter of the disk orifice formed therein communicating, at one end, with the orifice in said disk and terminating, at its other end, in the plane of the respective end face for changing the direction of a stream moving through the passageway when said rotatable disk orifice is out of registration with the orifices in said plates; and, means extending into said body and engaging said disk for rotating the latter.
Claim 3
Dependent Claim
42 words
Structure as specified in claim 1 and further including: gear teeth secured to the periphery of said disk, said means including a shaft journaled by said body, and a spur gear on said shaft meshing with gear teeth on said rotatable disk.
Claim 4
Dependent Claim
35 words
Structure as specified in claim 1 in which the grooves in said end faces are disposed in opposite alignment and are formed on a radius common to the axis of the orifice in said disk.
Claim 5
Dependent Claim
30 words
Structure as specified in claim 3 and further including: registration means visually indicating the relative position of the grooves and the orifice in said disk with respect to the passageway.
