Abstract

1275499 I C engine poppet valve seats SULZER BROS Ltd 25 Nov 1970 [2 Dec 1969] 56077/70 Heading F1B A renewable valve seat member 2 in a bore 3 in a cylinder head 1 is prevented from moving away from the cylinder by a shoulder 4 in the bore and towards the cylinder by at least one metal strip 7 supported between a shoulder 6' in the bore and a shoulder 8 on the outer surface of the seat member. The strip 7 has an end 7' accessible through an opening 16 in the seat member 2. Three strips 7 may be provided. A cooling water chamber around the seat member 2, communicating with the cylinder head cooling chamber through bores (13, 14), Fig. 2 (not shown), is bounded by resilient annular parts 10 and 11 containing soft seals 12, e.g. O-rings. The portion 3' of the bore 3 has a force fit with the seat member 2 and a clearance fit is provided for the remainder of the seat member.
