摘要： A fuel and air charge forming device, such as a carburetor, may include a main body, a fuel and air mixing passage in the body, a fluid passage communicating with the fuel and air mixing passage and a solenoid valve. The solenoid valve may include a coil and a valve body having a base fixed against movement and a valve head extending from the base. The valve head may be driven by the coil between a first position wherein the valve head at least partially obstructs the fluid passage and a second position wherein the valve head permits greater fluid flow in the fluid passage to control fluid flow through the fluid passage.

摘要： A carburetor has a throttle element rotatably supported on a throttle shaft and a choke element rotatably supported on a choke shaft. A first coupling element is fixedly connected to the throttle shaft. A second coupling element is connected to the choke shaft. The first and second coupling elements define in a locked position a start position of throttle element and choke element. The locked position is released by rotation of the throttle shaft in opening direction of the throttle element. The locked position is released by rotation of the choke shaft in opening direction of the choke element. One of the first and second coupling elements is an at least partially elastic coupling element. Upon rotation of the choke shaft from the locked position into an open position, the elastic coupling element is elastically deformed and releases the locked position between the first and second coupling elements.

摘要： A carburetor valve and limiter cap assembly for limiting adjustment of fuel flow in a carburetor may include a needle valve and a limiter cap. The needle valve may have a tip, a threaded portion, a head having a flange with an outer diameter greater than the rest of the head, and one or more serrations formed on the head. The limiter cap may have a sidewall, a tab extending outwardly from the sidewall, a first cavity having an inner diameter sized for an interference fit with the flange, and at least one driving feature to engage at least one serration so that rotation of the limiter cap causes rotation of the needle valve. The interference fit between the flange and the limiter cap inhibits removal of the limiter cap from the needle valve to prevent undesired adjustment of the needle valves by an end user.

摘要： An engine carburetor and a solenoid valve assembly therefor and methods of assembling the same. The carburetor has a body with a fuel and air mixing passage communicating with an air bleed passage. A cavity extends into the body for communication with the air bleed passage. A solenoid housing is received in the cavity and maintains a coil body for receipt of a valve body therein. The valve body moves between a retracted position to substantially open the air bleed passage and an extended position to substantially close the air bleed passage.

摘要： A carburetor valve control system for stabilizing engine warm-up operating conditions by automatically controlling the degree of opening of a throttle valve so as to be larger than a normal degree of opening for idling, without carrying out a special operation of appropriately strengthening the spring force of a governor spring. The carburetor throttle valve control system includes a throttle lever and a governor system coupled to the throttle lever. A choke return spring is connected to a choke lever, the choke return spring urging the choke lever to a choke valve closing side. An automatic choke system is disposed so as to face the choke lever. A throttle valve closure restricting member is provided between the throttle lever and the choke lever. During engine warming-up, when the spring force of a governor spring is adjusted to zero or a minimum, the choke lever restricts closing of the throttle valve via the throttle lever by means of the spring force of the choke return spring.

摘要： A carburetor arrangement for a two-stroke engine (1) is for a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine or the like and has an intake channel (22). The intake channel (22) is partitioned by a partition wall (11) into an air channel (8) and a mixture channel (21). A fuel opening (27, 28) for supplying fuel to the two-stroke engine (1) opens into the mixture channel (21). The carburetor arrangement has a carburetor (17) having a carburetor housing (18) wherein an intake channel section (32) is formed. A throttle flap (24) is pivotally journalled in the carburetor housing (18). A good partitioning of the air channel (8) from the mixture channel (21) results with a simple manufacture of the carburetor (17) when a partition wall section (31, 48, 58, 68, 78, 88, 98) is configured as a separate component upstream of the throttle flap (24) and is held in the intake channel (22).

摘要： A throttle valve device for use in an internal combustion engine comprises a valve shaft extending across an air induction passage of the engine. A valve plate is fixed to the valve shaft to rotate therewith in the air induction passage. An electric actuator is connected to one end of the valve shaft to rotate the valve shaft with the aid of electric power. A biasing cam structure is incorporated with the valve shaft to bias the valve place toward a predetermined intermediate open position. The biasing cam structure comprises a cam plate which is secured to the other end of the valve shaft to rotate therewith and has a generally V-shaped cam edge; a loading lever which has a base end pivotally connected to a fixed portion; a follower member which is connected to a leading end of the loading lever and slidably engaged with the V-shaped cam edge; and a biasing member which biases the loading lever in a direction to press the follower member against the V-shaped cam edge.
