Title (EN) FLOW CONTROL VALVE AND HYDRAULIC MACHINE INCLUDING THE SAME
(FR) VANNE DE RÉGULATION DE DÉBIT ET MACHINE HYDRAULIQUE LA COMPRENANT
Abstract:
(EN) A flow control valve is disclosed. A valve body has an inner circumferential surface defining a longitudinal bore to which at least a portion of first and second fluid passages is connected. A spool is slidably inserted into the bore to allow a flow of fluid from the first to second fluid passage. A valve regulates a flow rate of fluid flowing through the first fluid passage. A first seat surface is defined between an area in which the first fluid passage is connected to the bore and an area in which the second fluid passage is connected to the bore. When the flow of fluid from the first to second fluid passage is initiated, an area of a gap between the first seat surface and the spool on a plane taken in a transverse direction is 5%~50%, preferably 10%~20% of an area of an opening defined by the first seat surface.
(FR) L'invention concerne une vanne de régulation de débit. Un corps de vanne a une surface périphérique interne définissant un alésage longitudinal auquel au moins une partie des premier et second passages de fluide est reliée. Un tiroir est inséré de manière coulissante dans l'alésage de façon à permettre un écoulement de fluide du premier au second passage de fluide. Une vanne régule un débit d'écoulement de fluide s'écoulant à travers le premier passage de fluide. Une première surface de siège est définie entre une zone dans laquelle le premier passage de fluide est relié à l'alésage et une zone dans laquelle le second passage de fluide est relié à l'alésage. Quand l'écoulement de fluide du premier au second passage de fluide est déclenché, une surface d'un espace entre la première surface de siège et le tiroir sur un plan pris dans une direction transversale est de 5 % ~ 50 %, et, de préférence, de 10 % ~ 20 %, d'une surface d'une ouverture définie par la première surface de siège.
