    Abstract: A flow control valve which consists of a valve housing including a valve body having a straight cross bore therethrough, a pair of end covers which seal the bored hole at the sides of the valve body and which also serve as a bearing means to rotatably support a rectangular valve plate rotatively positioned within the bored hole, the valve body having a first hole extending through the valve body from one exterior surface thereof to run out at the cross bore and a contoured hole of continuous profile extending from a surface of the valve body to run out at the cross bore, the included angle in the cross bore of the fluid flow path between these holes with the valve plate in full open position relative to these holes being less than 180*.

    Abstract: A mass flow air meter for use in a mass air flow type electronic fuel injection system for an engine to measure mass air flow through an air induction system including a scheduled area valve consisting of a butterfly valve cooperating with scheduled valve throat area openings whereby the pressure drop in the induction passage through this valve is held approximately constant during changes in fluid flow by allowing the valve throat area openings to vary.

    Abstract translation: 一种用于发动机的质量空气流式电子燃料喷射系统的质量流量空气流量计，用于测量通过空气感应系统的质量空气流量，该空气感应系统包括由与预定的阀喉区域开口配合的蝶阀组成的预定区域阀，由此压力 通过允许阀门喉部区域开口变化，在通过该阀的进气通道中的下落在流体流动变化期间保持大致恒定。
