<p>PCT No. PCT/US79/00799 Sec. 371 Date Sept. 28, 1979 Sec. 102(e) Date Sept. 28, 1979 PCT Filed Sept. 28, 1979 PCT Pub No. WO81/00881 PCT Pub. Date Apr. 2, 1981 In some piston engines a pressurized fluid which is delivered to a main receptor (16) is also delivered to a secondary receptor (18) from which it is directed to cool the pistons. During engine startup and low idle operation such cooling is unnecessary, and further, it is desirable to provide as much fluid flow as possible to the main receptor (16), which is generally the main lubricating manifold (16) of the engine. Herein, delivery of the pressurized fluid to the secondary receptor (18) is prevented until the fluid pressure in the main receptor (16) reaches an initiating value (A). The main receptor (16) thus receives added fluid flow at startup and during low idle operation, while adequate piston cooling is provided at normal operating speeds.</p> |
