Abstract
Abstract A valve is presented which is capable of metering and dispensing a quantity of a thick liquid or slurry on a rapid production basis. The valve allows the slurry to move through it freely except for momentary interruption during the actual metering and dispensing cycle and thus the heavier or more solid components of the slurry do not tend to settle out nor collect in the valve as readily as they would otherwise. Also, the valve is simple to construct and maintain having but one moving part in the slurry which first rotates to close the valve to enclose an exact metered portion of the slurry and then translates to dispense it.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
116 words
A valve having a metering chamber substantially immersed in a viscous fluid flowing in a conduit, flow passage means through the valve and its metering chamber in communication with the conduit, a rotary closure member for the flow passage, an outlet in communication with the metering chamber only when the closure member has been rotated and the flow passage closed, a one-piece plunger and rotary closure member adapted to translate toward the outlet after the closure of said passage and the opening of said outlet, whereby that portion of the viscous fluid contained in the metering chamber after the closure of the passage means is forced through the outlet by the movement of the plunger theretoward.
Claim 2
Dependent Claim
116 words
A valve having a metering chamber substantially immersed in a viscous fluid flowing in a conduit, flow passage means through the valve and its metering chamber in communication with the conduit, a rotary closure member for the flow passage, an outlet in communication with the metering chamber only when the closure member has been rotated and the flow passage closed, a one-piece plunger and rotary closure member adapted to translate toward the outlet after the closure of said passage and the opening of said outlet, whereby that portion of the viscous fluid contained in the metering chamber after the closure of the passage means is forced through the outlet by the movement of the plunger theretoward.
Claim 3
Dependent Claim
27 words
The invention set forth in claim 1 with the ports in the valve body substantially aligned with the direction of flow of the fluid in the conduit.
Claim 4
Dependent Claim
54 words
The invention set forth in claim 2 with said rotary closure member comprising a hollow cylinder having oppositely disposed ports in its wall in communication with corresponding ports in the valve body with the member in a first position and blocking the ports in the valve body with the member in a second position.
Claim 5
Dependent Claim
56 words
The invention set forth in claim 3 with the outlet including a discharge port And at least one of the ports in the valve body in communication with the discharge port when the rotary closure member is in the second position and out of communication therewith when the rotary closure member is in the first position.
Claim 6
Dependent Claim
48 words
The invention set forth in claim 4 with the rotary closure and plunger member including a hollow cylindrical portion having an internal bore open at one end and blind at the other and a cylindrical outlet pipe received by said bore in rotary and translatory sliding relationship thereto.
