Abstract
A porting and ducting arrangement for a pair of adjacent hollow cylinders includes respective pluralities of passages extending longitudinally in the walls of the cylinders. Each passage is provided with a port in communication with the interior of the associated cylinder. Plural recesses in the end of the cylinders or in a cover are each in communication with a separate passage or group of passages when the cover is applied to the cylinders. There are a pair of such recesses thereby associated with each cylinder and at least one recess of each pair is in communication with a recess of the other pair via duct means in the cover. Gasket means is retained between the cylinders and the cover to seal each recess of each pair of recesses with respect to the other recess of the pair.
