hva[一種賽車用配件]

HVA是一般民用版汽車使用的液壓閥系統在賽車中，這是一種賽車用配件HVA系統能帶來兩個好處，第一是可減低發動機表現的偏差，可達百分之三；第二是不再需要向活瓣作出調節，直接節省成本。The invention relates to a hydraulic valve-play compensation element. 該發明涉及液壓閥系統。 The aim is to prevent any change in the length from taking place when the engine is at a standstill.這樣做的目的是防止發動機處於停滯時長度發生改變。 To this end, the leakage oil is guided into the space between the high pressure valve 4 and the valve 5, where it then reinforces the sealing effect of said valve 為此，泄漏的汽油將導入之間的空間高壓閥閥4和閥5 ，然後強化它的密封效果說。 When the engine is in operation, the valve 4 is kept open irrespective of the direction of throughflow by means for producing a defined force, for example a pressure-loaded piston or by electromagnetic means.當發動機在運行時，閥門4 ，不論是保持開放的方向穿越的方式確定的生產力量，例如壓力負載活塞或電磁手段
