Abstract
(EN)
An expansion valve has a valve main body (1), and in the valve main body (1) are arranged a first restriction section (5) and a second restriction section (6) on the downstream side of the first restriction section (5). The second restriction section (6) is constructed from the outer peripheral surface of a second valve body section (16) and the inner peripheral surface of a second valve hole (13). A spiral groove, a straight groove or other kind of groove is formed in the outer peripheral surface of the second valve body section (16) or in the inner peripheral surface of the second valve hole (13). Further, either the outer peripheral surface of the second valve body section (16) or the inner peripheral surface of the second valve hole (13) is tapered toward the tip of the valve body (4).

La présente invention concerne une soupape de dilatation qui comporte un corps de soupape principal (1), et dans le corps de soupape principal (1) sont agencées une première section de restriction (5) et une seconde section de restriction (6) sur le côté aval de la première section de restriction (5). La seconde section de restriction (6) est construite à partir de la surface périphérique extérieure d’une seconde section de corps de soupape (16) et la surface périphérique intérieure d’un second orifice de soupape (13). Une rainure en spirale, rainure droite ou rainure d’autre type est formée dans la surface périphérique extérieure de la seconde section de corps de soupape (16) ou dans la surface périphérique intérieure du second orifice de soupape (13). En outre, soit la surface périphérique extérieure de la seconde section de corps de soupape (16) soit la surface périphérique intérieure du second orifice de soupape (13) est effilée vers la pointe du corps de soupape (4).
