Abstract
A method for the manufacture of a valve having at least one valve opening surrounded by at least one valve seat and an elongated valve member able to be brought into different positions by pivoting. In order to adjust the switching stroke of the valve member the valve member is, for instance using a laser, locally and briefly heated until superficial plastification occurs so that in the direction of the pivoting movement performed in operation it experiences a permanent flexural deformation.
Claims17
A method for the production of a valve, which comprises at least one valve opening surrounded by a valve seat and furthermore an elongated valve member able to be positioned by pivoting selectively into a closing position with a closure section resting on the at least one valve seat or into an open position clear of the valve seat, wherein for adjustment of a switching stroke thereof the valve member is briefly locally heated for superficial plastification so that it experiences a permanent flexural deformation in the direction of its pivoting movement performed during operation.
