Scroll type booster

Abstract

A scroll type booster ensures a noiseless structure by reducing operation sound using a scroll type compressor as a booster and an easy start-up operation. An electromagnetic valve at an intake side is provided between an intake port of a compressor body and a pneumatic line at an intermediate position of an intake pipe. The electromagnetic valve is opened / closed by the control unit. When the valve is opened, a communication of the intake port of the compressor body and the pneumatic line is allowed. When the valve is closed, the communication between the intake port and the pneumatic line is blocked. Under a start-up control of the compressor body, the electromagnetic valve at the intake side is opened to communicate the pneumatic line in the plant with the intake port of the compressor body for power supply to an electric motor to drive an orbiting scroll. The rattle of the orbiting scroll by an amount equal to the axial gap (play) is suppressed before starting a compression operation.

Description

technical field [0001] The present invention relates to a turbocharger suitable for use as a supercharger, which is installed in connection with, for example, an air pressure line in a factory and boosts the pressure of a fluid such as air as needed. Background technique [0002] Generally, in a factory where a plurality of pneumatic equipment is installed, pneumatic piping (piping) is used to connect each pneumatic equipment, and the compressed air discharged from an air compressor used as a pressurized air source is sent to each pneumatic equipment through the pneumatic piping. The structure of the machine supply. Also, there is known a structure in which the air pressure in the pipeline is doubled by using, for example, a reciprocating compressor called a booster compressor on the downstream side of such a pneumatic pipeline (for example, refer to Patent Document 1). . [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-51614 [0004] However, this type of r...

However, in this case, it is inevitable to use a large and expensive electromagnet, which may not be realistic from the viewpoint of cost and effect.

[0013] Moreover, in such a case, since the electric wiring for supplying power to the electromagnet must be installed, for example, inserted into the fixed turbine side, the structure of the turbo compressor becomes complicated, and it is difficult to achieve small size and weight reduction.
