[0075] [First Embodiment: Basic Configuration]

[0076] Such as figure 1 As shown, the refrigerant control valve device V is installed in a vehicle, and is provided with: an inlet PS that receives cooling water (an example of refrigerant) from an engine E that is an internal combustion engine; The radiator hose 1 sends out to the radiator R; and the second discharge port P2 sends the cooling water to the heater tank H through the heater hose 2 . The engine E has a cylinder head Ea and a cylinder block Eb, and cooling water is supplied from the cylinder head Ea to the inlet PS of the refrigerant control valve device V. As shown in FIG. In addition, the cooling water supplied to the radiator R and the cooling water supplied to the heater tank H are sent from the water inlet valve 3 to the water pump 4 (W / P), and returned from the water pump 4 to the cylinder Eb of the engine E.

[0077] In addition, in this first embodiment, the cooling water from the refrigerant control valve...

[0123] In this second embodiment, the refrigerant control valve device V having the same structure as the previous embodiment is used, but the flow direction of cooling water (an example of refrigerant) is reversed, and the first seal part 15 and the second seal part 19 is structured differently. In addition, in this 2nd Embodiment, the structure different from 1st Embodiment is extracted and demonstrated, and the code|symbol common to 1st Embodiment is attached|subjected to the structure common to the said embodiment.

[0124] [Second Embodiment: Basic Configuration]

[0125] Such as Figure 12 As shown, the refrigerant control valve device V is installed in a vehicle and includes: a discharge port US (an example of a discharge part) that returns cooling water (an example of refrigerant) from an engine E that is an internal combustion engine to the engine E; An introduction port U1 (an example of an introduction port), which is supplied with cooling water for the radiator R via the radiator hose 1 ; and a second introduction port U2 (an example of an introduction port), which is supplied via the heater hose 2 Cooling water for warm air water tank H. The engine E has a cylinder head Ea and a cylinder block Eb, and cooling water is supplied from the cylinder head Ea to the outlet valve 5 . The outlet valve 5 is configured to divert the cooling water to the radiator R and the heater tank H. As shown in FIG. In addition, the cooling water from the discharge port US is sent to the water pump 4 ...

Abstract

This coolant control valve device, which can maintain good sealing while limiting size increase, is configured so that: a rotor is housed to rotate freely in a housing in which a first discharge port and a second discharge port with a smaller diameter are formed; holes for controlling the flow of coolant to the first discharge port and the second discharge port are formed in the outer wall of the rotor; and a second seal part of the second discharge port abuts against the edge of a hole when the rotor is set to either rotation position in which coolant is discharged to the second discharge port.

Description

technical field [0001] The present invention relates to a refrigerant control valve device in which a rotor for controlling the flow of refrigerant is rotatably housed in a housing having a discharge port. Background technique [0002] As a refrigerant control valve device, Patent Document 1 discloses a technique in which a rotor (a cross-section adjusting member in the document) is rotatably arranged inside a housing. In this patent document 1, the opening formed on the outer periphery of the rotor and the opening formed on the housing (in this document, the opening of the connecting pipe) overlap each other so that the refrigerant can flow between the inside of the rotor and the opening. flow. [0003] In this patent document 1, the rotor is formed in a spherical shape, and an opening opened in a direction along the rotation axis and a plurality of openings corresponding to the mouth are formed on the spherical outer wall surface. [0004] Patent Document 2 discloses a t...
