Title:
低圧力降下及び低漏れ性の回転式四方切換弁
Document Type and Number:
Japanese Patent JP6442515
Kind Code:
B2
Abstract:
The invention provides a rotary four-way reversing valve with low pressure drop and low leakage, comprising a valve body and a valve core arranged in the valve body through bearings. The valve body comprises a low-pressure exhaust tube, a high-pressure air inlet tube, a condenser tube and an evaporating tube. The valve core is slantingly divided by a U-shaped seal ring with a spring into a high-pressure chamber and a low-pressure chamber that are not communicated with each other. The valve core comprises a through hole arranged in the high-pressure chamber and aligned with the high-pressure air inlet tube of the valve body and an opening aligned with the condenser tube or the evaporating tube, an opening arranged in the low-pressure chamber and always aligned with the low-pressure exhaust tube and an opening aligned with the condenser tube or the evaporating tube.
