燃料调节设备
摘要：
一种燃料调节系统(10)包括限定出腔室(14)且配备有位于腔室(14)上游的入口(16)和位于腔室(14)下游的出口(18)的外壳(12)。外壳(10)中形成具有与入口(16)连通的第一端部(22)和与腔室(14)连通的第二端部(24)的半球形支座(20)。包括曲面(28)和横跨曲面(28)延伸的平表面(30)的阀体(26)被接收在支座(20)内。阀体(26)可在关闭位置和开启位置之间运动，在关闭位置，阀体(26)密封入口(16)，在开启位置，阀体与入口(16)分隔开，以使空气经位于支座(20)和曲面(28)之间的第一端部(22)并经位于第二端部(24)和阀体(26)的相邻部分之间的间隙(38)流入腔室(14)。弹簧(32)以约1大气压的压力将阀体偏压向关闭位置。
摘要（英）：

A fuel conditioning system (10) comprises a housing (12) defining a chamber (14) and provided with an inlet (16) upstream of the chamber (14) and an outlet (18) downstream of the chamber (14). A hemispherical seat (20) is formed in the housing (10) with a first end (22) in communication with the inlet (16), and a second end (24) in communication with the chamber (14). A valve body (26) is received within the seat (20) and comprises a curved surface (28) and a planar surface (30) that extends across the curved surface (28). The valve body (26) is moveable between a closed position where the valve body (26) seals the inlet (16) and an open position where the valve body is spaced from the inlet (16) to allow air to flow through the first end (22) between the seat (20) and curved surface (28), and through a gap (38) formed between the second end (24) and an adjacent portion of the valve body (26), into the chamber (14). A spring (32) biases a valve body at a pressure of approximately one atmosphere toward the closed position.
