Abstract: PURPOSE:To reduce the stress added to a communicating pipe and improve working property by providing a steel band having a spring part for pressing the communicating pipe into contact with a cylinder head through an oil capillary. CONSTITUTION:A cylinder head 4 having an inserting hole 4a provided on a compression element 3, an inlet muffler 10 having a communicating pipe 11 inserted to the inserting hole 4a, an oil capillary 13 having one end opened into a lubricating oil 12 reservoir and the other end opened into the communicat ing pipe 11, and a steel band 14 having a spring part 14a for pressing the com municating pipe 11 into contact with the cylinder head through the oil capillary 13 are provided. After the communicating pipe 11 is inserted to the inserting hole 4a of the cylinder head 4, the oil capillary 13 is installed and pressed into contact with the cylinder head 4 by the steel band 14. Hence, when the communicating pipe 11 is formed of a material having low heat conductivity such as synthetic resin, the stress at the time of installation can be reduced, and working property can be improved.

Abstract: PURPOSE:To improve the operability and reduce the cost by mounting a glass terminal connected to a motor on a closed container, integrally assembling electrical components including an operation capacitor and mounting these components to the glass terminal. CONSTITUTION:A closed container 21 contains both a compression element and a motor. The closed container 21 has a glass terminal 24 to which a motor is connected. Electrical components including an operation capacitor 2 are assembled integrally and attached to the glass terminal 24. A fixing screw used when the operation capacitor 2 is mounted, a cap used for protecting an electrically charging part and wires which connects the operation capacitor 3 to a unit board 1 are unnecessary. Therefore, the operability may be improved and the cost be reduced.
