Abstract:
A rotary device for receiving fluid input and generating a fluid discharge therefore, said rotary device comprising:(a) a stationary outer housing having a circumferential outer wall comprising a first outer surface and a second opposing annular inner surface; (b) a rotatable cylinder housing positioned within said outer housing, said cylinder housing comprising a generally annular outer surface disposed toward and positioned in generally close juxtaposition with at least a portion of the second inner surface of said outer housing, said cylinder housing including a central opening therein and a plurality of open cylinders defining passages extending from the central opening generally to the outer surface of said cylinder housing, said rotatable cylinder housing defining a first central axis of rotation; (c) a rotatable wheel positioned within said central opening, said rotatable wheel defining a second axis of rotation of said rotatable wheel displaced from the first axis of rotation; and (d) a plurality of pistons connected to said rotatable wheel, and extending into respective ones of the open cylinders thereby to define closed fluid processing chambers between said pistons and the inner surface of said outer housing, said rotatable wheel, said pistons, and said rotatable cylinder housing being cooperatively designed and configured to rotate substantially in unison within said stationary outer housing whereby said pistons move in reciprocating paths along longitudinal axes of said cylinders such that sizes of spaces within the cylinders between top sides of said pistons and the tops of said fluid processing chambers alternately increases and decreases,said rotary device further including a cylinder head in a respective said cylinder proximate the outer surface of said cylinder housing, said cylinder head comprising a solid structure having a first top side and a second generally opposing bottom side, said first top side being disposed toward said second inner surface of said outer housing.
