摘要： A refrigerant compressor has a member forming a compression chamber with a discharge port and a discharge reed valve. The reed valve has a valve cover portion at one end for opening and closing the discharge port and a portion at another end that is fixed to the member. A valve restricting plate is fixed to the member forming the compression chamber together with the fixed portion of the discharge valve so as to overlie the reed valve and to restrict the opening amount of the reed valve cover portion. The valve restricting plate has a head portion wider than a middle portion thereof which head portion opposes the valve cover portion of the discharge valve against which it can come into contact A through hole or notch is provided in the restricting plate head portion to provide back pressure flow communication that acts on the cover portion of the reed valve to prevent it from sticking to the valve restricting plate.

摘要： An object of the present invention is to provide a multi-cylinder rotary compressor which can enhance the reliability by improving the compression efficiency/mechanical efficiency. The bearings are fixed on the inner wall of the closed container, the cylinders are fixed to the bearings, and a gap is formed between the respective cylinders and the inner wall of the closed container. The design with the relatively large internal volume of the closed container is possible, and the reliability can be enhanced. Further, improvement in the compression efficiency and the mechanical efficiency can be achieved with the compact multi-cylinder rotary compression element.
