摘要： An apparatus for adjusting the air-fuel ratio of a fuel mixture to be supplied to an engine. The apparatus has a pair of needle valve bodies and a pair of receptacles formed in a main body of a carburetor for receiving the needle valve bodies. Each needle valve body has a needle and a head. The needles are axially movable relative to a respective needle orifice. The needles may be axially advanced and retracted by rotating the needle valve bodies within the receptacles to respectively decrease and increase the flow of the fuel mixture around the needles and through the orifices. To prevent tampering with the needle valve body setting, the head of the needle valve body has an unconventional shape requiring a specialized tool to rotatably adjust the needle valve body. To further prevent tampering, the head is recessed with the main body of the carburetor. A retainer is disposed in the main body of the carburetor and receives the needle valve bodies to facilitate maintaining alignment of the needle valve bodies relative to the receptacles. The retainer assures that a constant fuel calibration setting is maintained through the orifices by resisting displacement of the needles due to such factors as external forces applied to the head of the needle valve body or engine vibration.
摘要翻译：一种调节供给发动机的燃料混合物的空燃比的装置。该设备具有一对针阀体和形成在化油器的主体中的一对接收器，用于接收针阀体。每个针阀体都有针头和头部。针可相对于相应的针孔轴向移动。针可以通过旋转插座内的针阀体来分别减少和增加燃料混合物在针和通过孔的流动而轴向前进和缩回。为了防止针阀体设置的篡改，针阀体的头部具有非常规的形状，需要专门的工具来可旋转地调节针阀体。为了进一步防止篡改，头部与化油器的主体凹陷。保持器设置在化油器的主体中并接收针阀体，以便于保持针阀体相对于容器的对准。保持器确保通过阻止针的位移由于诸如施加到针阀体的头部的外力或发动机振动的因素而保持恒定的燃料校准设置。

摘要： A carburetor having an idle nozzle and a main nozzle each with a fixed flow area and an idle speed single adjustment screw adjustable by the user. The idle and high speed fuel flows are controlled by the idle nozzle and the main nozzle, respectively. The user can adjust the engine speed only by adjustment of the idle speed adjustment screw which changes the position of the carburetor throttle valve to control the flow through the carburetor. This provides a more consistent fuel and air mixture to improve the performance of the engine and better control engine emissions by preventing the user from changing the fuel and air ratio to a mixture which is either too lean or too rich for the steady and low level exhaust emission operation of the engine.

摘要： A carburetor in which no deviation or change occurs in the adjusted position of a fuel regulating needle valve and when a cap for limiting the adjustment is mounted on the fuel regulating valve the cap cannot be intentionally broken or removed. A flow area of a fuel pasage of a carburetor body is adjusted by a needle valve received in a threaded hole in the body. Adjacent the threaded hole the carburetor body has a cylindrical cavity having a larger diameter than that of the threaded hole. A larger-diameter threaded portion is provided on the needle valve adjacent its head. A stop ring in contact with a shoulder in the cylindrical cavity is fitted on the larger-diameter threaded portion of the valve. A cup-shaped cap is fitted on the serrated head of the fuel regulating valve. An axial protrusion formed on the outer peripheral wall of the cap is engaged with an axial groove opening into the peripheral wall of the cylindrical cavity. A retaining plate having an opening through which the cap can be inserted is fixed to the outer end wall of the cylindrical cavity of the carburetor body.

摘要： A carburetor with an idling system is designed so that the full pressure differential or gradient available between approximately ambient pressure and the vacuum in the intake tube is employed for producing a critical pressure ratio of a supersonic flow in a laval nozzle. To make this possible, a fuel air emulsion formed with primary air is introduced from a mixing duct via a constricted orifice of a tubular nozzle at a bore constriction, at which there is always a sonic velocity when there is a critical and supercritical pressure ratio, into the secondary air flow where it is superfinely atomized in the secondary air flow, with a maximum velocity differential, aided by subsequent pressure surges. At least at a point far into the partial load range of operation, the idling system produces a homogeneous mixture which is homogeneously distributed in the intake tube with a practically molecular state of division so that it is even supplied to all cylinders of the engine and completely combusted with a minimum production of contaminants.

摘要： A carburetor for small motors has a housing with a carburetor bore wherein air and fuel are mixed to an air fuel mixture. The fuel enters the carburetor bore through fuel jets. A throttle valve is pivotally mounted in the carburetor bore by means of which the fuel-air mixture quantity is adjusted in dependence upon the operating condition of the engine. The throttle valve and the inner wall surface of the carburetor bore conjointly define an air gap in the idling position. An idling fuel outlet jet communicates with the carburetor bore in the region of this air gap and is connected to the control chamber containing the fuel. The idling fuel outlet jet together with a ventilation bore communicate with an emulsion chamber of the control compartment. Further, an idling control part is provided which is movable into the air gap whereby an outlet opening of the ventilation bore communicating with the emulsion chamber is passed over. In this way, the ratio of fuel to air in the emulsion chamber can be adapted to the air requirements when flowing into the carburetor bore from the outlet jet. By means of a change of the free cross-sectional opening of the ventilation jet occurring simultaneously with the entry of the control part into the air gap, the air to fuel ratio remains constant so that a subsequent adjustment of the components of the mixture is unnecessary.
摘要翻译：用于小型电动机的化油器具有带有化油器孔的壳体，其中空气和燃料与空气燃料混合物混合。燃油通过燃油喷射进入化油器孔。节流阀枢转地安装在化油器孔中，通过该节气门，燃料 - 空气混合物量根据发动机的操作条件进行调节。节流阀和化油器孔的内壁表面联合地限定空转位置的气隙。空转的燃料出口喷射器与该气隙区域中的化油器孔连通并连接到包含燃料的控制室。空转燃料出口喷射器和通风孔与控制室的乳剂室连通。此外，设置有可移动到空气间隙中的空转控制部，通过与乳化室连通的通气孔的出口。以这种方式，乳液室中的燃料与空气的比例可以适应于从出口喷射器流入化油器孔中时的空气需求。通过与控制部件进入气隙同时发生的通气射流的自由横截面开口的变化，空气/燃料比保持恒定，使得混合物的组分随后的调整是不必要的。

摘要： An adjust screw device for use with a carburetor of an internal combustion engine having stops for restricting the range within which the automobile user can readjust the idle R.P.M. by adjusting the adjust screw at the carburetor. The adjust screw device is composed majorly of a first adjust screw having a large adjustable range and a second adjust screw for fine adjustment, the physical position of the second adjust screw being changed by the adjustment of the first adjust screw. After initial adjustment of the first adjust screw by the manufacturer, further adjustment of the screw is completely blocked and the second adjust screw is then adjustable by the user only over a predetermined range.
