COMPRESSOR WITH GAS STATIC SUSPENSION OF PISTON AND PSEUDOPOROUS FEEDERS Russian patent published in 1997 - IPC

FIELD: mechanical engineering; compressors. SUBSTANCE: compressor has cylinder with piston installed in cylinder with clearance and pseudoporous feeders in form of capillary slots formed at contact of rough surfaces of piston and cylinder sleeve members pressed to each other and connected with supply source and clearance between piston and cylinder to build carrying gas layer. Above-indicated members form, all together, gas static suspension of piston with end face surfaces communicating with low pressure area. Average height of rough surface microirregularities is found from equation where Ra is mean height of microirregularities; b is radial clearance between piston and cylinder; D is cylinder diameter; L is distance from extreme slot of gas static suspension to its end face surface; N is number of members with rough end face surfaces located at one side of axis of symmetry of piston gas static suspension; P is pressure on above-indicated members; S is yield point of member material D₁ and d are outer and inner diameters of members, respectively. EFFECT: enlarged operating capabilities. 3 dwg
