Abstract
The ball point comprises a body having a front surface and a housing emerging in an opening in the front surface and communicating with a passage supplying a fluid. A ball can rotate freely in the housing. The body front surface has a peripheral portion parallel to the median plane of the opening and a flared portion adjacent to the opening periphery which forms at the point of contact of the ball with the opening periphery an acute angle (alpha) with the emerging part of the plane tangent to the ball at the contact point.
