Abstract

568,458. Valves. SANDERS, A. F. Oct. 14, 1943, No. 16901. [Class 7 (vi)] [Also in Group XXIX] A valve seat insert comprises a relatively hard seating 21 firmly secured to a rubber or other resilient damper element 22 which is also secured to a hard backing element 23. The seating may extend around the inner face of the damper element 22 and the backing 23 be embedded centrally therein. In other forms, the backing extends up the outer face of the element which, in all forms, provides the sole interconnecting means between the seating and the backing.
