Abstract: A housing (30) for use in high pressure fluid applications comprising a first drilling (32a, 32b), defining a first axis, and having a region of enlarged diameter (32b) bounded by an upper boundary (36) in a first plane and a lower boundary (38) in a second plane; and a second drilling (42), defining a second axis, and intersecting with the first drilling (32a, 32b) via an intersection region (44). The intersection region (44) includes a first substantially flat surface (54) which defines a ceiling of the intersection region (44) and which intersects the upper boundary (36) of the region of enlarged diameter (32b), and a second substantially flat surface (56) which is opposed to the first substantially flat surface (56) and which defines a floor of the intersection region (44) and intersects the lower boundary (38) of the region of enlarged diameter (32b). As the flat surfaces are in alignment with a region of maximum hoop stress (i.e. at the upper and lower boundaries of the enlarged diameter region of the first drilling) they do not act as a significant stress raiser at the intersection (44). In another aspect of the invention the first drilling need not have a region of enlarged diameter, with the intersection region having tangential surfaces to the circumference of the first drilling so that the intersection region does not intersect with a region of hoop stress.

Abstract: A pump assembly (30) for use in an internal combustion engine comprises a pump housing (32a, 32b) provided with a bore (34) within which a pumping plunger (36) is reciprocal along a plunger axis; a pump chamber (38) defined at one end of the bore (34) within which fuel is pressurised to a relatively high level as the pumping plunger (36) reciprocates within the bore (34), in use; and an inlet valve (40, 40a, 40b) housed within the pump housing (32a, 32b) and in communication with the pump chamber (38) to control the flow of fuel into the pump chamber (38). A clamp member (46) applies a clamping load to the pump housing (32a, 32b), which has at least a component that is aligned with the plunger axis, through a surface of the pump housing located approximately axially above the bore (34). This has the effect of generating a compressive stress in the pump housing in close proximity to the plunger bore (34) to counter tensile stress within the pump housing due to pressurised fuel within the pump chamber (38). The clamp member (46) may be secured to the pump housing (32a, 32b) by at least one securing member (48), which may be positioned radially outwards from the bore (34) and extend through or below a plane through the pump chamber (38) and perpendicular to the plunger axis through the pump chamber (38).
