Abstract
PURPOSE:To accomplish efficient control of the capacity of a compressor, by connecting a by-pass port formed in a cylinder to a suction pipe via a by-pass pipe, and providing a solenoid valve capable of opening and closing the by-pass port such that the by-pass port is closed at the time of full-load operation of the compressor and opened at the time of unloaded operation. CONSTITUTION:A capacity controlling mechanism for an enclosed type motor driven compressor, of this invention, comprises a by-pass port 5 opened in a cylinder 2, a by-pass pipe 10 communicating the by-pass port 5 to a suction pipe 3, a valve 9 for opening and closing the by-pass port 5 at a position near the opening end of the same, a valve driving means (solenoid valve) 6 fixed to a casing 1, and a means (valve rod) 9a for connecting the valve driving means 6 to the valve 9. That is, when the by-pass port 5 is closed by operating the valve 9 by the valve driving means 6, full-load operation of the compressor is performed. On the other hand, when the port 5 is opened, coolant gas drawn into the cylinder 2 is by-passed to the suction pipe 3 via the by-pass pipe 10, so that unloaded operation is performed. Thus, it is enabled to control the capacity of a compressor in a highly efficient manner.
