Problems solved by technology

However, if such a flange portion is formed, the flange portion overlaps the first port 102 and the second port 103 in the cooling mode and the heating mode (the first position and the second position of the spool 105), and there is a high pressure side. The flow of refrigerant is hindered by the flange, resulting in a decrease in the flow rate
In addition, it is also conceivable to increase the respective distances of the first port 102 and the second port 103 relative to the outflow port 101, but this leads to an increase in the size of the slide switching valve 100, so it is not recommended

Embodiment Construction

[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Such as figure 1 As shown, the refrigeration cycle 1 of this embodiment is used in an air conditioner such as a room air conditioner, and includes a compressor 2 that compresses a refrigerant, and an outdoor heat exchanger as a first heat exchanger that functions as a condenser in the cooling mode. 3. In the cooling mode, the indoor heat exchanger 4, which functions as an evaporator as the second heat exchanger, expands the refrigerant between the outdoor heat exchanger 3 and the indoor heat exchanger 4 to depressurize it as an expansion unit. The expansion valve 5 of the mechanism, the four-way switching valve 10 as a sliding switching valve, and the pilot solenoid valve 6 for switching and controlling the flow path of the four-way switching valve 10 are connected through refrigerant piping.

[0046] In addition, the expansion mechanism is not limited to the expansion ...

Abstract

The invention provides a slide type switch valve and refrigerating cycle system, wherein the system can reduce middle flow in mode switching, can easily obtain pressure difference for switching modes, and can prevent a high pressure side and lower pressure side flow reduction in a cooling mode and a heating mode; In the four-way switching valve (10), the valve member (24) of a spool (12) has a concave bowl portion (25) and a flange portion (26) extending outwardly; one side of the flange portion is provided with a first inner protrusion (27A) protruding to the bowl portion and a first outer protrusion (28A) protruding to the outer side, and the other side is provided with a second inner protrusion (27B) and a second outer protrusion (28B); In the first passing position, the first inner protrusion and the first outer protrusion are spaced apart from the inside of the peripheral edge of the first port (11C) by a predetermined gap; In the second passing position, the second inner protrusion and the second outer protrusion are spaced apart from the inner side of the peripheral edge of the second port (11D) by a predetermined gap.

Description

technical field [0001] The invention relates to a sliding switching valve and a refrigeration cycle system. Background technique [0002] Conventionally, as a refrigeration cycle used in an air conditioner such as a room air conditioner, a refrigeration cycle in which the circulation direction of the refrigerant is reversed is used so that the refrigerant passes through the compressor and the outdoor heat exchanger during the cooling mode (cooling) operation. , expansion valve, and indoor heat exchanger to circulate to the compressor, and to circulate the refrigerant to the compressor through the compressor, indoor heat exchanger, expansion valve, and outdoor heat exchanger during heating mode (heating) operation . As a flow path switching valve (so-called four-way switching valve) that reverses the circulation path of the refrigerant in such a refrigeration cycle, a slide type switching valve provided with a spool slidably provided inside the valve body is widely used. . ...
