Abstract:
A pulsation dampening apparatus for providing a selectively variable orifice size fir a reciprocating compressor system includes a rotatable conical cage and a fixed conical cage, the conical cages being aligned along a central axis to firm a central cylindrical port. The conical cages each include at least one window or port and have mating contours allowing the conical cages to rotatably slide over one another, allowing their respective ports to be selectively aligned in any configuration to create any desired effective orifice size. In one embodiment, each of the conical cages include a plurality of ports which can be selectively aligned, the relative alignment of the ports determining the effective orifice size of the pulsation dampening apparatus.

Claim (Index 7):
A pulsation dampening apparatus for providing a variable effective orifice size for a reciprocating compressor, the pulsation dampening apparatus comprising;\n a) a fixed inner conical cage including a plurality of inner conical cage ports; b) a rotatable outer conical cage including a plurality of outer conical cage ports; c) a central cylindrical port created by alignment of the inner conical cage and the outer conical cage about a central axis, wherein the inner conical cage and the outer conical cage have mating contours allowing the rotatable outer conical cage to slide over the fixed inner conical cage as it rotates about the central axis, rotation of the outer conical cage causing the plurality of inner conical cage ports and the plurality of outer conical cage ports to be selectively aligned, the relative alignment of the plurality of inner conical cage ports with the plurality of outer conical cage ports determining the effective orifice size of the apparatus; and d) a bevel gear drive including a shaft having rotatable gear teeth, the outer conical cage further including a flange including fixed gear teeth which engage the rotatable gear teeth, wherein rotation of the rotatable gear teeth causes the outer conical cage to be rotated, rotation of the outer conical cage causing a change in the orientation of the plurality of outer conical cage ports with respect to the plurality of inner conical cage ports, thereby allowing adjustment of the apparatus to any desired effective orifice size.
