Abstract
According to one aspect, a rotary exhaust valve system includes an arcuate ring having a first plurality of apertures and a rotary valve ring disposed in an overlapping relation with the arcuate ring. The rotary valve ring has a second plurality of apertures forming therein corresponding to at least some of the first plurality of apertures. A first crank is disposed in a first side of the rotary exhaust valve system, and a second crank is disposed in a second side of the rotary exhaust valve system. The second crank is connected to the first crank and the rotary valve ring, and the first crank actuates the second crank and moves the rotary valve ring such that openings of the first plurality of apertures are closed and opened.
Claims18
A rotary exhaust valve system, comprising:
- an arcuate ring having a first plurality of apertures therein;
- a rotary valve ring disposed in an overlapping relation with the arcuate ring, the rotary valve ring having a second plurality of apertures formed therein corresponding to at least some of the first plurality of apertures;
- a first crank disposed in a first side of the rotary exhaust valve system;
- and
- a second crank disposed in a second side of the rotary exhaust valve system, the second crank connected to the first crank and the rotary valve ring, wherein the first side is separated from the second side via a separation member, wherein a crankshaft passing through the separation member connects the first crank to the second crank, wherein the first crank actuates the second crank and moves the rotary valve ring to align the at least some of the second plurality of apertures with the at least some of the first plurality of apertures forming openings that are closed and opened by movement of the rotary valve ring.
A fluid extraction system including an exhaust valve system, comprising:
- a first member having a first plurality of apertures therein;
- a second member having a second plurality of apertures therein, the second member disposed adjacent to the first member;
- an actuation unit comprising an actuator connected to a first crank disposed on a first side of the exhaust valve system, a second crank disposed on a second side of the exhaust valve system connected to the first crank;
- a separation member separating the first side from the second side;
- and
- a crankshaft passing through the separation member connecting the first crank to the second crank, whereby the actuation unit is operatively connected to the second member and configured to align at least some of the second plurality of apertures with respect to the first plurality of apertures such that a predetermined flow of exhaust fluid can pass through the at least some of the aligned first and second plurality of apertures.
A rotary exhaust valve system for testing operation of a compressor, the rotary exhaust valve system comprising:
- an O-ring having a first aperture formed therein;
- a rotary valve ring disposed in an overlapping relation with the O-ring, the rotary valve ring having a second aperture formed therein;
- and
- an actuator unit having an actuator arm, a first crank, a second crank, and a spacer disposed between and connecting the actuator arm and the first crank;
- wherein the first crank is connected to the second crank via a crank shaft passed through a separation member separating a first side from a second side of the rotary exhaust valve system;
- wherein the second crank is further connected to the rotary valve ring to adjust alignment of the second aperture with respect to the first aperture, whereby an opening between the first and second aperture is adjusted based on size of the spacer.
