Title:
VARIABLE VALVE DEVICE
Document Type and Number:
Japanese Patent JP2017180400
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a variable valve device including a cam switching mechanism easy in assembling work with a simple structure of a small number of components by making switching pins mechanically advance and retreat through a cam mechanism.SOLUTION: In a variable valve device including a cam switching mechanism (70) for switching cam lobes (43A, 43B) by axially moving a cam carrier (43) fitted to an outer periphery of a cam shaft (42) so that one of them acts on a valve (41), the cam switching mechanism (70) includes switching pins (73, 74) advancing and retreating to be engaged with and disengaged from a lead groove (44) of the cam carrier (43), and a switching driving shaft (71) engaged with the switching pins (73, 74) by configuring a cam mechanism (Ca). The switching pins (73, 74) advance and retreat by driving of the switching driving shaft (71) through the cam mechanism (Ca), and the cam carrier (43) is axially guided and moved while rotated by the lead groove (44) with which the switching pins (73, 74) are engaged by advancing, to switch the cam lobes (43A, 43B) so that one of them acts on the valve (41).SELECTED DRAWING: Figure 11
