Patent ID: 7823289

Claim:
A method for producing multiple valve housings ( 11 ) by cutting respective multiple sections ( 12 , 13 , 14 ) from a billet material ( 10 ) extruded in an elongate extent thereof and by working into each of the sections inlet and outlet conduits ( 27 , 28 , 29 , 30 ) substantially arranged in a common plane and a receiving bore ( 20 ) for at least one valve element ( 21 , 26 ) extending transversely to the inlet and outlet conduits and substantially arranged in the common plane, characterized in that the billet material ( 10 ) is shaped as a substantially parallelepiped base body with ribs ( 15 , 16 , 17 , 18 ) which project outwardly and at which ribs the inlet conduits ( 27 , 29 ) and outlet conduits ( 28 , 30 ) open, wherein the inlet conduits ( 27 , 29 ) and the outlet conduits ( 28 , 30 ) and the receiving bore ( 20 ) are formed in the billet material ( 10 ) transversely to the elongate extent thereof for each of the multiple sections ( 12 , 13 , 14 ) and thereafter the billet material ( 10 ) is cut transversely between the sections ( 12 , 13 , 14 ) to produce discrete individual valve housings ( 11 ).
