Injection hydraulic automatic advance device

摘要: A hub 1 integral with the injection pump to include a housing 2 driven in rotation, surrounding and including two rollers 4, 5 placed parallel axis of at distance from this axis. An eccentric governor weight 15 is mounted on be able move one direction under action centrifugal force. Two advance control pistons 8, 9 orthogonal axes are hub, each slide recessed bore equipped lateral support ramp 10, 11 work cause an angular offset between 2. One 8 acts other by spring 18. hydraulic circuit goes through has distributor controlled relief 20 adjusting pressure acting as function position 15. additional piston 32 modifies balance prevailing circuit. correction device temperature fluid can also provided.
