Piston machine

Abstract

A machine proposed for use in energy producing industry as an engine, a pump and a compressor. The machine has a crankcase 1, a cylinder 2, and a piston 3 and a piston rod 4, two crankshafts 6 and 7 rotating in opposite directions. An inner hollow 12 of the piston communicates with a throughgoing axial passage 13 of the piston rod 4 located in the crankcase with the possibility of a reciprocating movement in a suction pipe 14; wherein the passage 13 of the piston rod is formed with a diffusor 27 from the side of the hollow 12 of the piston 3 and with a confusor 28 from the side of the suction pipe 14. Pumping valves 18 are arranged on the cover 5 of the cylinder, and suction valves 16 are arranged on the front wall of the piston; wherein the piston rod 16 and the connecting rods 10 and 11 of the crankshaft 6 and 7 are hingedly connected with a traverse 29. The invention provides a reduction of a waste space and reduction of hydraulic losses.

Description

technical field [0001] The invention relates to the field of mechanical construction and can be used in compressors, pumps and internal combustion engines. Background technique [0002] Piston machines are known which have a crankcase on which a cylinder is fastened and a cover arranged on the cylinder, wherein a piston with a piston rod is arranged in the cylinder. A connecting rod system with a crosshead is connected to the crankshaft and has a guide in the lower part of the crankcase (certificate no. 905499 of the inventor's USSR, FO1B9 / 00 1978). [0003] A disadvantage of the known piston machine is that it does not solve the problem of reducing wasted space, reducing hydraulic losses in the valves and insufficient cooling of the machine's piston, which reduces its volumetric productivity. [0004] Piston machines are known which have a crankcase on which the cylinders are fixed and covers arranged on the cylinders, suction and pumping valves, two parallel crankshafts, ...

AI Technical Summary

Problems solved by technology

[0005] A disadvantage of the known piston machine during its use as a compressor is the occurrence of a significant waste of space, as well as during the suction and pumping of the working body due to the positioning on one cover of the cylinder of the suction and pumping valve The hydraulic loss increases the minimum volume between the cover and the piston due to the volume of the valve and reduces the flow cross-section of both the suction valve and the pumping valve which together occupy the same surface of the cover, which reduces the piston mechanical Volumetric productivity and filling of cylinders with working bodies

Also, sufficient cooling of the piston is not provided in this piston machine
