摘要： A pump head suitable for use in a fuel pump for a common rail fuel injection system, comprises a pump head housing defining a plunger bore and a pumping chamber. Fuel is pressurized within the pumping chamber by a plunger reciprocating within the plunger bore. The pump head housing includes an inlet valve arrangement for controlling fuel flow into the pumping chamber. The inlet valve arrangement includes a valve member movable between open and closed positions in response to fuel pressure within a gallery. The gallery communicates with an external chamber defined by a closure means externally mounted to the pump head housing. In use, the gallery communicates with a source of low-pressure fuel via the external chamber. The pump head housing has a projection which locates the closure member on the pump head housing.

摘要： A valve assembly for use in a fuel pump comprises a body member with a valve aperture, a valve member movable within the body member and adapted to close the valve aperture, and a biasing arrangement having a first part fixed with respect to one of the body member and the valve member and a second part fixed with respect to the other of the body member and the valve member. The biasing arrangement is adapted to bias the valve member to close the valve aperture. The biasing arrangement comprises a helical spring with a first diameter at the first part and a second diameter at the second part. The first diameter of the helical spring is different from the second diameter of the spring. The helical spring is at its first part retained by an interference fit against the member with respect to which it is fixed.

摘要： A housing for use in high-pressure fluid applications, comprising a first passage defining a first axis (P1) and a second passage defining a second axis (P2), wherein the first and second passages intersect at an opening defined by an intersection at one end of the second passage. When sectioned on a plane normal to the second axis (P2) and not intersecting the first passage, the intersection defines an ellipse (E) in the plane and centred on the second axis (P2), the ellipse having a major axis equal in length to the width (D2) of the intersection and a minor axis equal in length to the height (D1) of the intersection. A wall of the intersection describes a curve in the plane, the curve passing through the points where the major and minor axes of the ellipse (E) meet the perimeter of the ellipse (E), and through points which lie outside the ellipse (E) and which are offset from the ellipse (E) by an offset distance (K).
