Scroll compressor, refrigerating cycle device, and heat pump water heater
2009
When not sufficiently oil-tight compression chamber can not be sufficiently compressed refrigerant, it can not improve efficiency. That is, from the efficiency point of view, how to become a subject of oil seal. Object of the present invention, the suction chamber by the backpressure control valve is disposed in the inside of the side when the orbiting scroll and the orbiting scroll side of the suction chamber outside this intermittent communication start position increases the volume of communication between the two sides to achieve. Further, the tooth tip is achieved by the compression chamber via the supply space is provided than the tooth root fixed scroll on the deeper position.
