Abstract
Herein described is a frame for a fluid machine of the reciprocating type. The frame bears one or more cylinders moving inside each of which, with a reciprocating movement, is a piston operated by a crankshaft. The frame is made up of one or more modules of the same size and shape, within each one of the modules being provided a single chamber adapted to accommodate the crank mechanisms of each single cylinder. Each module is further provided with a pair of opposite side walls and with one or more fixing means which allow rigid coupling to each other, adjacently arranging their respective side walls, of two or more of the identical modules for providing a frame for fluid machines provided with two or more cylinders.
Claims20
A reciprocating compressor, comprising:
- a frame comprising two modules of the same size and shape, each of the two modules having a pair of sidewalls and a single chamber forming a cylinder;
- a piston disposed in the cylinder;
- a crankshaft extending through the pair of sidewalls of the two modules;
- and
- a fastener extending through the pair of sidewalls of the two modules to rigidly couple the two modules together to position one of the pair of sidewalls on each of two modules adjacent to one another.
A fluid machine for compressing fluids, said fluid machine comprising:
- a first module comprising a first sidewall and forming a first chamber with a first piston disposed therein;
- a second module coupled to the first module and having the same size and shape, the second module comprising a second sidewall that is adjacent to the first sidewall, the second module forming a second chamber with a second piston disposed therein;
- a crankshaft extending through the first module and the second module;
- and
- a fastener extending through the first sidewall and the second sidewall to rigidly couple the first module to the second module.
A compressor, comprising,
- a frame comprising a plurality of modules of the same size and shape, each of the plurality of modules having a sidewall and a chamber, wherein the plurality of modules are rigidly affixed to one another by fasteners extending through the plurality of modules;
- a piston disposed in the chamber of each of the plurality of modules;
- and
- a crankshaft extending through the plurality of modules.
