Description

technical field

[0001] The invention relates to a rotary compressor used in air conditioners, refrigerators and heat pump water heaters, in particular to a controllable compressor whose capacity can be switched between single-cylinder and double-cylinder displacement. Background technique

[0002] In the existing capacity-controlled compressors, holes communicating with the suction and exhaust chambers are generally set on the upper and lower cylinder heads of the single-stage compressor cylinders, and the solenoid valves are used to control the opening and closing of these holes to realize capacity control. ; There are also two or more compressors connected in parallel to achieve capacity control. These capacity control methods are complex in technology, poor in reliability, and high in overall cost, making them difficult to apply in practice. Contents of the invention

[0003] The purpose of the present invention is to propose a single- and double-cylinder capacity cont...
