    摘要： A hermetic compressor includes a closed vessel for storing lubricating oil, an electric-driving element, and a compressing element driven by the electric-driving element. The compressing element includes a cylinder block forming a compression chamber, a piton that reciprocates inside the compression chamber, and an oiling device for supplying the lubricating oil to an outer circumference of the piston. A first oil groove is concavely formed on the outer circumference of the piston, and a second oil groove is concavely formed on a side opposite to the compression chamber relative to the first oil groove. The second oil groove has a spatial volume same or greater than that of the first oil groove. An expanded clearance portion is provided such that a clearance between the piston and the cylindrical hole portion broadens from a top dead point to a bottom dead point.

    摘要： In a sealed compressor (100) of the present invention, a suction muffler (160) includes a communication pipe (162) coupled to a suction hole (151a) of a valve plate (151). The communication pipe (162) extends upward from the suction muffler (160) toward the other end of a cylinder (133), and is provided at an upper end thereof with a communication pipe exit section (162a) which is in communication with the suction hole (151a). The cylinder head (152) is formed on a lower portion with a recess (152d) accommodating the communication pipe exit section (162a) therein. A gas inflow space (152b) in the interior of the sealed container is formed between the communication pipe exit section (162) and a recess (152d). The gas inflow space (152b) in the interior of the sealed container is a space which is in communication with a sealed space inside of the sealed container (101).
