    • The nozzle according to the invention is characterized in that it comprises means (61, 62, 63) so that the dimensions of the fluid passage orifice vary as a function of the pressure differential between the inlet and the outlet. To this aim, the nozzle of the invention comprises a flat portion (30, 40, 50, 60) wherein are made at least two cuts (33, 45, 52, 62, 63) which form at least one tongue (31, 41, 51, 61) susceptible of elastically bending under the action of the fluid. Each cut is comprised of two grooves (61, 69) parallel to each other, one on each face of the flat portion, and of a slot (610) with a length equal to that of the grooves. Application: fabrication of nozzles and/or devices of which the flow rate is directly proportional to the pressure differential existing between the inlet and the outlet.
    • 根据本发明的喷嘴的特征在于其包括装置(61,62,63),使得流体通道孔口的尺寸随入口和出口之间的压力差而变化。 为此,本发明的喷嘴包括平坦部分(30,40,50,60),其中形成至少两个形成至少一个舌部(31,41)的切口(33,45,52,62,63) ,51,61)在流体的作用下易于弹性弯曲。 每个切口由彼此平行的两个凹槽(61,69),平坦部分的每个表面上的一个以及具有与凹槽的长度相等的长度的槽(610)组成。 应用:制造喷嘴和/或装置,其流量与入口和出口之间存在的压差成正比。

    • A carburetor may have a fuel metering assembly with a metering valve and a metering diaphragm sealed to a body of the carburetor to at least partially define a metering chamber with a portion of the metering diaphragm movable relative to the body to actuate a fuel metering valve. The diaphragm may include a continuous layer, a discontinuous layer, and an intermediate layer received at least partially between the continuous and discontinuous layers and at least partially inhibiting direct contact between the continuous and discontinuous layers. The continuous and discontinuous layers may be different polymer materials and the intermediate layer may be a polymer different than that of the discontinuous layer. The intermediate layer may include voids, segments, or a wire form.
