Abstract

FIELD: gas refrigerating machines operating by Sterling cycle. SUBSTANCE: in starting the motor, the working gas being compressed enters gas bottle from compression chamber due to pressure drop; gas flows through valve device making sealing rings move towards surface of EXPULSION rod forming tight contact, thus providing for reliable seal of rod. When motor is stopped, compressed gas is bypassed from bottle to working volume of refrigerating machine due to pressure drop through hole of smaller diameter in body of ball of valve device. EFFECT: effective dynamic gas seal of EXPULSION rod. 1 dwg

Изобретение относится к газовым регенеративным машинам, работающим по циклу Стирлинга. Достигаемый технический результат - эффективное динамическое газовое уплотнение штока вытеснителя. При пуске двигателя сжимаемый рабочий газ из полости сжатия за счет перепада давления поступает в газовый баллон через клапанное устройство, вызывая перемещение уплотнительных колец к поверхности штока вытеснителя и их плотное соприкосновение, обеспечивая надежное уплотнение штока. При остановке двигателя сжатый газ перепускается из баллона в рабочий объем холодильной машины за счет перепада давления через отверстие малого диаметра в теле шарика клапанного устройства.The invention relates to gas regenerative machines operating on the Stirling cycle. The technical result achieved is an effective dynamic gas seal of the displacer rod. When the engine is started, the compressible working gas from the compression cavity, due to the pressure differential, enters the gas cylinder through the valve device, causing the sealing rings to move to the surface of the displacer rod and their tight contact, providing reliable seal of the rod. When the engine is stopped, compressed gas is transferred from the cylinder to the working volume of the refrigeration machine due to the pressure difference through the small diameter hole in the body of the ball of the valve device.
