F02B33/06 - CPC Classification

Classification description:

Engines characterised by provision of pumps for charging or scavenging; Engines with reciprocating-piston pumps; Engines with crankcase pumps with reciprocating-piston pumps other than simple crankcase pumps

Sub-classes:

F02B33/08 » with the working-cylinder head arranged between working and pumping cylinders 5
F02B33/10 » with the pumping cylinder situated between working cylinder and crankcase, or with the pumping cylinder surrounding working cylinder 6
F02B33/18 » with crankshaft being arranged between working and pumping cylinders 11
F02B33/20 » with pumping-cylinder axis arranged at an angle to working-cylinder axis, e.g. at an angle of 90 degrees 20
F02B33/22 » with pumping cylinder situated at side of working cylinder, e.g. the cylinders being parallel 176
