Abstract

1456495 Crossheads; connecting rods; lubricating SULZER BROS Ltd 21 March 1975 [21 March 1974 11916/75 Headings F2T F2A In a crosshead bearing 3, e.g. for a diesel engine, in which an oil film is maintained in the most heavily loaded zone (B, Figs. 3 and 11, not shown) without the use of a high pressure lubricating pump, a valve periodically prevents oil from escaping from the zone (B). In one form (Figs. 1-8), the valve is a non-return valve 27. The valve 27 remains closed while the lubricant pressure (P L , Fig. 7, not shown) in the zone (B) is greater than the lubricant supply pressure (P O ). When (P L )<(P O ), valve 27 opens to allow the lubricant in the zone (B) to be replenished. In the other form (Figs. 9-16), the valve is an intermittently closed rotary sleeve valve (40, Figs. 12-14, not shown). The lubricant is supplied to tubes (10, 14, 15, Fig. 1, not shown, 10, 41, 42, Fig. 9, not shown) by a pump (8), which provides an uninterrupted flow of lubricant (as in Figs. 12, 15 and 16, not shown) through duct 26 in the connecting-rod 4 to the crank-pin bearing.
