Abstract

"IMPROVEMENTS IN THE MECHANICAL DEVICES FOR THE EXTRACTION OF VALVES", characterized by organizing such devices based on a main body, fixed at will in the cylinder head, which has an articulated joint to a tilting part, which, in its part upper, has the end of a threaded rod provided on its other end with a maneuvering member for its activation, while on such a rod is concentrically mounted a sliding piece, operable at will, internally threaded, by which the height is regulated that in relation to the fixing area of the former main body in the cylinder head, it must adopt an oscillating arm, also operable at will, which for this purpose is presented, by one of its ends, linked in an articulated manner with an auxiliary body incorporated to said sliding piece, whose body is fixed longitudinally while rotationally rotating in the sliding piece. , with the particularity that said oscillating arm has an elongated perforation of predetermined length, which can be traversed longitudinally in both directions by a transverse axis to which the appropriate extractor legs are attached, which are capable of oscillating substantially around of such a common axis, which is also provided with auxiliary fixing means by which the immobilization of the legs is determined in the part of that bore of the oscillating arm, immobilization established in advance, in consideration of the existing separation, in each case, between the fixing area of the aforementioned main body in the cylinder head and the situation of the valve to be extracted.
