Title: Four way type reversing valve for reversible refrigerating cycle
Inventor: ISOBE MASAKAZU
IPC: F16K31/42
Filed: 1985-03-25
Abstract: PURPOSE:To produce a four way type reversing valve for reversible refrigerating cycle which has stabilized function and miniaturized dimensions by opening a pressure equalizing hole by means of a driving pin working in accordance with the motion of a plunger when a pressure relief hole has been closed. CONSTITUTION:When an electric current is sent to an electromagnetic closing valve 16, and a compressor 4 is actuated, a plunger 17 is attracted to cause a ball valve 18 to open a pressure relief valve hole 3a, and a pressure transducing chamber R2 therefore communicates with the lower pressure inlet side of the compressor 4. In this case, since a ball valve 12c comes into strong contact with a valve seat 12b to close a pressure equalizing hole 12a, differential pressure to overcome the elastic force of a compression spring 13 occurs between chambers R1, R2 to move a piston 12 or a slide valve 21 toward a plug body 3. A through hole 11a is connected with a through hole 11b through the slide valve 21. Since even low differential pressure can establish the transduced position of the piston or slide valve, this valve is suitable for a four way type valve for the defrosting circuit of hot gas bypass system.
