Document Type and Number:
WIPO Patent Application WO/2018/070761
Kind Code:
A1
Abstract:
The present invention relates to a four-way valve for switching a refrigerant channel, the valve comprising: a housing part including a refrigerant filling chamber which is filled with a refrigerant; a valve plate disposed at one side of the housing part and having at least three inflow/outflow holes formed therein; a valve pad part disposed in the refrigerant filling chamber, rotating to contact one of surfaces of the valve plate, and occupying one of the at least three inflow/outflow holes in a constitutive manner and one of the remaining holes of the at least three inflow/outflow holes in a selective manner so as to make the occupied inflow/outflow holes communicate with each other, thereby forming a changed flow channel; a rotation driving part for transferring a driving force to rotate the valve pad part; and a deceleration part, disposed between the rotation driving part and the valve pad part, for increasing a driving torque transferred from the rotation driving part.
