摘要： Existing poppet valves have a tendency to rebound or bounce during operation. This rebound or bounce adversely affects engine governability, high pressure injector fuel flow, noise and idle stability. The present invention reduces or nearly eliminates poppet valve (52) rebound or bounce. The apparatus (161) for compensating for the rebound of bounce overcomes the problem of variable injection. For example, as the poppet valve (52) rebounds the weight (174) strikes the bottom or contacting surface (168) preventing the poppet valve (52) from moving toward the first position (156). Thus, the variation in the injection of fuel is prevented or eliminated. Additionally, with the variation in the injection of fuel eliminated, the adverse affects of the bounce or rebound enables better engine governability, high pressure injector fuel flow and idle stability with reduced noise.
