F01L1/00 - CPC Classification

Classification description:

Valve-gear or valve arrangements for positive-displacement machines or engines other than steam engines, e.g. for internal-combustion piston engines, without provision for variable fluid distribution

Sub-classes:

F01L1/02 » Valve drive 185
F01L1/12 » Transmitting gear between valve drive and valve 55
F01L1/20 » Adjusting or compensating clearance 219
F01L1/26 » characterised by the provision of two or more valves operated simultaneously by same transmitting-gear; peculiar to machines or engines with more than two lift-valves per cylinder 292
F01L1/28 » characterised by the provision of coaxial valves; characterised by the provision of valves co-operating with both intake and exhaust ports 31
F01L1/30 » characterised by the provision of positively opened and closed valves, i.e. desmodromic valves 51
F01L1/32 » characterised by the provision of means for rotating lift valves, e.g. to diminish wear 26
F01L1/34 » characterised by the provision of means for changing the timing of the valves without changing the duration of opening {and without affecting the magnitude of the valve lift} 811
F01L1/36 » peculiar to machines or engines of specific type other than four-stroke cycle 25
F01L1/44 » Multiple-valve gear or arrangements, not provided for in preceding subgroups, e.g. with lift and different valves 3
F01L1/46 » Component parts, details, or accessories, not provided for in preceding subgroups 507
