Abstract:
1. A housing for use in high-pressure fluid applications, the housing being provided with: a first passage defining a first axis (P a second passage defining a second axis (P wherein: a third axis (P the first and second passages intersect at an opening defined by an intersection at one end of the second passage; and the intersection defines a first internal dimension (D the intersection being shaped so that, when sectioned on a plane normal to the second axis (P 2 ) and not intersecting the first passage, the intersection defines: an ellipse (E) in the plane and centred on the second axis (P a rectangle (M) with a first vertex on the first axis (P a diagonal (H) which passes through the first vertex and the fourth vertex of the ellipse; wherein: a wall of the intersection describes a curve in the plane, the curve passing through the second vertex and the third vertex of the rectangle (M) and a point which is outside the ellipse (E) and which lies on a line (J) which extends from the first vertex of the rectangle (M) and at an angle (L) from the diagonal (H); and the point is offset from an intersection of the line (J) with the ellipse (E) by an offset distance (K).
