Изобретение относитс к области компрессоростроени .The invention relates to the field of compressor engineering.

Известен герметичный компрессор, содержащий блок цилиндров и картер с маслоотстойником 1 .Known hermetic compressor containing a cylinder block and crankcase with an oil sump 1.

Данный компрессор вл етс наиболее близким к изобретению по технической сущности и достигаемому результату.This compressor is closest to the invention in its technical essence and the achieved result.

Однако в данном компрессоре не обеспечиваетс достаточна очистка масла от примесей .However, this compressor does not provide sufficient oil cleaning from impurities.

Целью изобретени вл етс повыщение надежности устройства путем улучиюни очистки масла.The aim of the invention is to increase the reliability of the device by improving oil cleaning.

Это достигаетс тем, что в маслоотстойнике расположен диск с воронкообразными отверсти ми, закрепленный на днище картера и образующий с последним отстойную камеру и кольцевую щель; к нижней части блока цилиндров прикреплен щиток, перекрывающий диск.This is achieved by the fact that a disk with funnel-shaped holes is mounted on the bottom of the crankcase and forms a settling chamber and an annular gap with the latter; to the bottom of the cylinder block is attached plate covering the disk.

На чертеже изображен предлагаемый компрессор, продольный разрез.The drawing shows the proposed compressor, a longitudinal section.

Компрессор содержит блок 1 цилиндров и картер 2 с маслоотстойником 3. В маслоотстойнике 3 расположен диск 4, снабженный воронкообразными отверсти ми 5 и оСразующий с картером 2 отстойную камеру 6 и кольцевую щель 7. К нижней части блока 1 цилиндров прикреплен щиток 8.The compressor contains a block 1 of cylinders and a crankcase 2 with an oil sump 3. In the oil sump 3 there is a disk 4 equipped with funnel-shaped holes 5 and a settling chamber 6 and an annular slot 7 attached to the crankcase 2.

Claims

During compressor operation, oil from the friction units flows into the cavity formed by the flap 8, where partial sedimentation of mechanical impurities from the oil occurs. The remaining mechanical impurities are carried by the flow of oil into the oil sump 3 and through the annular gap 7 into the settling chamber 6, where they settle. The oil purified in this way from the top of the oil sump 3 enters the lubrication of the compressor friction units. In order to prevent mechanical particles from the settling chamber 6 from getting into the oil, going for lubrication in the disk 4, funnel-shaped holes 5 are provided. improved oil cleaning. Claim 1. A hermetic compressor comprising a cylinder block to a crankcase with an oil sump, characterized in that, in order to increase reliability by improving oil purification, a disk with funnel-shaped holes is mounted on the bottom of the crankcase and form 68. g. w, s with last settling chamber and annular gap. 1. A compressor according to claim 1, characterized in that a shield covering the disc is attached to the lower part of the cylinder block.
