Oil delivery prevention device for horizontal type rotary compressor

Abstract

An oil delivery prevention device for a horizontal type rotary compressor for use in a refrigerating system. The device effectively separates the mixed gas into oil and refrigerant gas and prevents the oil from delivery along with the refrigerant gas to the refrigerating cycle. The oil delivery prevention device comprises at least three oil separating nets placed in a motor outer space inside a compressor casing and spaced out at regular intervals. Each of the first and third nets comprises a doughnut net part, a shielding plate provided on a center hole of the doughnut net part and an oil port formed on a lower center of the doughnut net part. The second oil separating net comprises a doughnut shielding plate, a net part provided on a center hole of the doughnut shielding plate and an oil port formed on a lower center of the doughnut shielding plate. The spaces formed between the spaced nets prevent interference between the refrigerant gas and the oil. The oil ports of the nets are formed on the same height positions such that they are leveled and communicate with each other.
