Variable volume chamber for fluid machine utilized as e.g. pump, formed by arrangement of external gears whose pinions rotate in same direction in homokinetic manner, where axes of rotation of pinions are parallel to each other
摘要
<p>The chamber is formed by an arrangement of external gears. Pinions of the external gears rotate in a same direction in a homokinetic manner. Axes of rotation (O1-O3) of the pinions are parallel and equidistant to each other. The pinions are identical to each other and equal number of teeth. Shapes of the tooth in a plane perpendicular to an axis are an involute of a circle. Each pinion comprises three teeth for three axes of rotation or two teeth for four axes of rotation. Propellers of the pinions exhibit same angle and same direction.</p>
