Abstract (en)
[origin: WO9301399A1] A recuperative engine valve system (10) for an internal combustion engine. The system (10) includes an engine valve (12) having a plunger surface (16), a first means (20) for biasing the engine valve (12) towards its closed position, a source of relatively low pressure fluid (22), a source of relatively high pressure fluid (24), and a second means (28) for selectively communicating fluid between the plunger surface (16) and one of the low pressure fluid source (22) and the high pressure fluid source (24). The timing of the selective communication of low pressure fluid and high pressure fluid to the plunger surface (16) during valve displacement is controlled so as to preserve and recuperate energy.
