Description

実施形態の回転式圧縮機は、シリンダ室を形成するシリンダと、前記シリンダ室内に偏心回転自在に収容されたローラと、前記シリンダに形成されたブレード溝に摺動可能に設けられ、先端部が前記ローラの外周面に当接するブレードと、シリンダの端面に設けられた前記シリンダ室を塞ぐ側板と、を備える。一つの前記側板に複数の吐出孔を設け、前記複数の吐出孔のうち前記ブレードから遠い吐出孔が前記ブレードに近い吐出孔よりも前記シリンダ室の中心に近い位置に設けられるとともに、前記ブレードから遠い吐出孔は、前記ブレードが前記シリンダ室に最も突出した下死点に位置したときに、前記ローラの端面と重なることなく、前記シリンダ室に対向して開口するように設けられる構成とする。 The rotary compressor of the embodiment is slidably provided in a cylinder that forms a cylinder chamber, a roller that is housed in the cylinder chamber so as to be eccentrically rotatable, and a blade groove that is formed in the cylinder. A blade that contacts the outer peripheral surface of the roller; and a side plate that closes the cylinder chamber provided on an end surface of the cylinder. A plurality of discharge holes are provided in one side plate, and among the plurality of discharge holes, a discharge hole far from the blade is provided at a position closer to the center of the cylinder chamber than a discharge hole close to the blade, and from the blade The distant discharge hole is provided so as to be opposed to the cylinder chamber without overlapping with the end face of the roller when the blade is located at the bottom dead center where the blade protrudes most into the cylinder chamber .

Claims

A cylinder that forms a cylinder chamber, a roller that is housed in the cylinder chamber so as to be eccentrically rotatable, and a blade that is slidably provided in a blade groove formed in the cylinder, and whose tip is in contact with the outer peripheral surface of the roller And a rotary compressor provided with a side plate that closes the cylinder chamber provided on the end surface of the cylinder,
A plurality of discharge holes in one of said side plates, distant discharge hole from the blade among the plurality of discharge holes are provided at a position close to the center of the cylinder chamber than the discharge holes closer to the blade Rutotomoni, the blade When the blade is located at the bottom dead center that protrudes most into the cylinder chamber, the discharge hole far from the nozzle hole is provided so as to be opposed to the cylinder chamber without overlapping the end surface of the roller. And rotary compressor.
