Abstract: A method of high pressure die casting in iron alloy reinforcements for main bearing scantlings in an aluminum alloy engine block for an internal combustion engine. Prior to casting, reinforcements (1) having bores (6) for main bearing screws are placed in a die cavity (21), so that cores for main bearing screws protrude into the bores in each reinforcement on one side of the reinforcement. Then the reinforcements are fixed in the die cavity by placing a cylinder liner core (25) against a surface (27) of the reinforcement on the opposite side of the reinforcement.

Abstract: The invention relates to a pressure regulating valve comprising a valve body having one or more inlet openings and one or more outlet openings for a pressurized medium, an internal cavity connecting said inlet and outlet openings and a piston which is in contact with a valve seat between inlet and outlet and is axially slidable in the cavity in the valve body against a spring, which biases the piston to a closed position, whereby the valve opens when a predetermined pressure acts on the piston. The valve body is provided with an opening at its outlet side, where the cross-section of the opening is smaller that the cross-section of the cavity and which opening is in connection with a volume limited by the piston and the lower section of the internal cavity, whereby the pressure drop across the valve dampens variations in the volume.

Abstract: A main bearing cap (20) for an internal combustion engine consists of an aluminum alloy with an iron alloy core (10). The cap has a supporting surface (22) for a bearing shell. The iron alloy core has a central portion (13) with two spaced apart through-channels (15) filled with an aluminum alloy (24) forming a coherent mass with an aluminum layer (23) the outer limiting surface of which forms the supporting surface (22).
