Title:
ELECTRONIC EXPANSION-AND-REDIRECTION INTEGRATED VALVE
Document Type and Number:
WIPO Patent Application WO/2021/066356
Kind Code:
A1
Abstract:
The present invention relates to an electronic expansion-and-redirection integrated valve. More particularly, the present invention provides an expansion valve capable of switching not only to a closed state in which the flow of a refrigerant is blocked, but also to an expansion state in which an expansion gap is formed so as to expand the refrigerant or to a fully open state in which the refrigerant is circulated without being expanded. The expansion valve comprises: a valve body (100) having a block shape and having a channel (110) formed therein such that an input port (101) and an output port (102) communicate with each other; a rotary valve (200) provided to be able to rotate in the circumferential direction inside the channel (110), the rotary valve (200) having an expansion recess (210) and a channel hole (220) formed therein; a valve plate (300) having a through-hole (310) formed therein; an airtight member (400) made of an elastic airtight material and integrally provided on at least one surface of the rotary valve (200) to be able to rotate toward the valve plate (300), thereby securing airtightness between the through-hole (310) of the valve plate (300) and the rotary valve (200); and a driving member (500) for delivering rotary power to the rotary valve (200). Accordingly, precise control is enabled while simplifying the configuration of a vehicle air conditioner. Particularly, airtightness regarding the refrigerant, and processability and productivity regarding the product are improved, thereby lowering the product production cost and maximizing market competitiveness.
