Abstract

406,945. Cooling cylinders. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Sept. 26, 1933, No. 26492. Convention date, Sept. 27, 1932. [Class 7 (ii).] Cooling air is forced by a blower 4 into chambers 7, 8, whence it is evenly distributed to the cylinders by slots 11, 12 which vary in width so that more air is supplied to the head ends of the cylinders. The jackets 9, 10 butt on to the cooling fins, which are shorter on the inlet than on the outlet side, where further slots 13, 14 allow the air to flow out past push rods 28, 29 of the overhead-valve gear. The chambers 7, 8 are integral with the crank-case which is egg-shaped in section as shown. Further air is discharged adjacent the exhaust valve housings 22<1> which are of good heatconducting material. In a modification as applied to an upright V-engine, the air is delivered to the space between the lines of cylinders at the opposite end to the blower and leaves outside the rows of cylinders in the direction of the blower.
