发明名称 Pneumatic valve return spring
摘要 A valve spring device using pressurized gas for use in biasing a reciprocating valve which moves between a seated position and open position. The device features a static housing having a static chamber what is translateably engaged with dynamic housing. Chambers inside both housings are sealably engaged such that the dynamic housing translates away from the static housing when pressurized gas is communicated to the engaged sealed chambers thereby biasing the dynamic housing away from the static housing and moving the attached valve. Timing of oscillation of the translation and resulting valve timing is controlled by a controller activating a control valve between a pressurizing state and a venting state. The timing may be adjusted to accommodate the engine timing through varying the controller's activation of the control valve and optionally varying the pressure of the gas using a regulator.
