摘要：An engine valve assembly (10) within an electrohydraulic camless valvetraincooperates with a hydraulic system (8) having a low pressure branch (70) and a highpressure branch (68) to selectively open and close engine valve (12). Engine valve (12) isaffixed to a valve piston (16) within a piston chamber (18). A volume (42) below piston (16)is connected to high pressure branch (68) and a volume (20) above piston (16) is
selectively connected to the high pressure branch (68) or the low pressure branch (70) viaa rotary valve (34), to effect engine valve opening and closing. A motor (60) effects therotation of the rotary valve (34).
