PHASE CHANGING DEVICE FOR CAMSHAFT Russian patent published in 2015 - IPC F01L1/34 F01L1/356 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engines. The gas distribution phase changing device 100A is offered which is installed on the distributive shaft (DS) 10 which is rotated by the input driving force and comprises the internal shaft 11 and the external shaft 12. The device 100A comprises the assembly 1A which includes the uniform housing 2 forming the hydraulic chamber R1 of acceleration providing acceleration of the phase DS 10 in general; the hydraulic lag chamber R2 providing lag of the phase DS 10 in general, and the hydraulic chamber R3 of phase angle providing change of difference between the phase of the internal shaft 11 and the phase of the external shaft 12. The device functions at the expense of hydraulic pressure supplied to liquid device chambers.

EFFECT: technical result consists in decrease of dimensions and cost of the gas distribution phase changing device, and also optimisation of regulation of gas distribution phases.
