Abstract

The invention relates to the field of compressor engineering and is an improvement of the invention according to the author. St. No. 737643. The aim of the invention is to increase the economy by reducing oil consumption. A through hole 6 is made in the cylinder 4 cylinder liner in the section intersected by the piston 5 at the bottom dead center. An annular groove is made at the section of the piston 5 blocking the holes 6 at the upper dead point. As a result of this design, the gas does not penetrate into the oil cavity 3 and does not create in it an overpressure that prevents the oil from draining into it from the suction cavity 2 through the bypass holes 7, which prevents the oil from being carried away from the suction side. cavity. 1 il. / 7 ////////// 7 7 // ///. sl 0; about

This invention relates to the field of compressor operation at the time of

compression compressor, maybe an is-cycle compression part of the gas is broken

used in piston compressors through a piston ring 8, falls into

and is an improvement to the image gap between cylinder 4 and piston 5,

reteni auth. № 737643. 5i flows through the gap in the ring

The purpose of izbretenn is the upper groove 10, from which, when combining efficiency by reducing the gap with the holes 6, the gas enters the oil course. The suction cavity 2. Due to this figure, the compressor is shown, the gas does not penetrate into the oil general form. Vol. 3 and does not create in it the overpressure Compressor contains a block and crankcase of first pressure, which prevents the pumping of the suction 2 and oil 3 cavities — to drain the oil into it from the suction cavities communicated between themselves and the firing cavity 2 through the bypass pipes. crankcase 1 in the vertex 7, and thereby prevents

through holes 6. The suction formula of invention 2 is communicated with the oil cavity. A piston compressor according to author. 3 bypass holes 7. Piston 737643, characterized by 5 is equipped with sealing rings, which, in order to increase economic efficiency, and 9, and additionally at least by reducing oil consumption, at least one annular groove 10,., the piston is provided with at least one located in the area of the hole 6 gilkoltsev groove located zi qi, pindra 4 in the area of the piston 5, in the area of the cylinder liner openings on blocking apertures 6 in upper, a site of the piston, blocking from the dead point (ВМТ). tee at top dead center.
