摘要： A bridge assembly is disclosed for use with an internal combustion engine. The bridge assembly may have a valve bridge, a cylindrical housing disposed within the valve bridge, and a plunger disposed in the cylindrical housing and protruding from the valve bridge. The bridge assembly may also have a valve housing, a post located inside the valve housing, a plurality of obliquely angled ports passing through a straight annular wall portion of the valve housing, and a plurality of radially oriented ports passing through a tapered annular wall portion of the housing. The bridge assembly may further have a valve seat disposed at least partially inside the plunger, a ball disposed within the valve housing and movable between a distal end of the post and the valve seat, a first spring disposed over the post, and a second spring disposed within the cylindrical housing.

摘要： A valve bridge assembly is disclosed for an internal combustion engine. The assembly may have a valve bridge with a center portion, opposing lateral extensions, a bore passing through first and second ends of the center portion, and an internal annular shelf. The assembly may also have a cylindrical housing with a main portion, a tip portion protruding from the second end of the center portion, and a positioning flange resting on the internal annular shelf. The assembly may further have a plunger with a first end having a larger opening and a second end having a smaller opening. The first end may be disposed within the main portion of the cylindrical housing, and the second end may protrude from the first end of the center portion. The assembly may also have a valve assembly disposed within the larger opening of the plunger, and a spring disposed inside the cylindrical housing.
