INTEGRATED VALVE

An integrated valve constitutes a part of a fluid circulation circuit through which a predetermined fluid circulates. When a first valve body (72) of the integrated valve is moved in an axial direction along an axis, the first valve body (72) is switched between a first communication state in which...

Zusammenfassung:	An integrated valve constitutes a part of a fluid circulation circuit through which a predetermined fluid circulates. When a first valve body (72) of the integrated valve is moved in an axial direction along an axis, the first valve body (72) is switched between a first communication state in which a first inlet passage is connected to a first outlet passage and a second inlet passage is closed, and a second communication state in which the second inlet passage is connected to the first outlet passage and the first inlet passage is closed. Also, when moved in the axial direction, a second valve body (74) of the integrated valve is switched between an open state in which a predetermined fluid from a third inlet passage is caused to flow to the second outlet passage, and a throttled state in which the flow of the predetermined fluid from the third inlet passage is more throttled than in the open state and the predetermined fluid is caused to flow to the second outlet passage. Further, when the first valve body and the second valve body are moved in the axial direction, the valve activation section (76) of the integrated valve is switched between a first activation state in which the first valve body is set to the first communication state and the second valve body is set to the open state, and a second activation state in which the first valve body is set to the second communication state and the second valve body is set to the throttled state. L'invention concerne une vanne intégrée, qui constitue une partie d'un circuit de circulation de fluide à travers lequel circule un fluide prédéterminé. Lorsqu'un premier corps de vanne (72) de la vanne intégrée est déplacé dans une direction axiale le long d'un axe, le premier corps de vanne (72) est commuté entre un premier état de communication, dans lequel un premier passage d'entrée est relié à un premier passage de sortie et un deuxième passage d'entrée est fermé, et un second état de communication, dans lequel le deuxième passage d'entrée est relié au premier passage de sortie et le premier passage d'entrée est fermé. En outre, lorsqu'il est déplacé dans la direction axiale, un second corps de vanne (74) de la vanne intégrée est commuté entre un état ouvert, dans lequel un fluide prédéterminé provenant d'un troisième passage d'entrée est amené à s'écouler vers le second passage de sortie, et un état étranglé dans lequel l'écoulement du fluide prédéterminé provenant du troisième passage d'entrée est plus étrangl
