Title:
CLOSED TYPE MOTOR-DRIVEN COMPRESSOR
Document Type and Number:
Japanese Patent JP3129103
Kind Code:
B2
Abstract:

PURPOSE: To reduce the generation of vibration of a refrigerant pipe and propagation of the vibration from the refrigerant piping to the whole of a device and to reduce the generation of vibration and noise by providing a support member to support a closed type motor-driven compressor between approximately the same as the mounting position, where a refrigerant piping and a connection piping are attached to a closed container, or the axis of a rotary shaft and the connection piping.
CONSTITUTION: In a horizontal closed motor-driven compressor, a suction pipe 2a is arranged at one end part of a cylindrical closed container 1 and the connection piping of a delivery pipe 2b is arranged at the other end face part. The centers R and R of support points supported by support members 10 and 10 are caused to approximately coincide with the axis of each connection piping. Each of the support members 10 and 10 has two holes in which resilient support bodies 11, such as vibration insulation rubber or a vibration insulation spring, are installed, and mounted on a freezing device through the resilient support bodies 11. The suction pipe 2a is arranged in a position lower than that of a center of gravity G of the closed container 1 and meanwhile, the delivery pipe 2b is disposed in a position higher than that of the center of gravity of the closed container 1.
