摘要： A breather and separator assembly for an engine. The engine includes a crankcase, a cylinder communicating with the crankcase, and a piston coupled for reciprocation in the cylinder. The engine includes a rotating shaft and a crankcase wall that includes a stationary aperture fluidly connected to an air/fuel induction system. The breather and separator assembly is separate from the shaft and adapted to be rotatable with the shaft. The breather and separator assembly includes a first side, an opposite second side, and an outer edge between the first and second sides. The first side is adapted to face the crankcase wall and has an annular groove adapted to be in fluid flow communication with the aperture during rotation of the rotating shaft. The breather and separator assembly also includes at least one radial passageway extending between the annular groove and the outer edge.

摘要： An internal combustion engine includes an engine housing and a crankshaft supported for rotation within the engine housing and rotatable in a starting direction to start said engine. At least one cup is fixedly mounted to the crankshaft for rotation therewith. A starter shaft is supported by the engine housing for rotation. A spring housing includes a circumferential flange that defines an annular track with the at least one cup, and a spring is housed within the spring housing. The spring has a first end interconnected with the spring housing and a second end interconnected with the engine housing. A friction roller is movable into the annular track and into engagement with both of the circumferential flange and the at least one cup to cause rotation of the spring housing and loading of the spring in response to rotation of the crankshaft. A unidirectional clutch is interconnected between the spring housing and the starter shaft, the unidirectional clutch causing rotation of the starter shaft in a starting direction in response to unloading of the spring, but not causing rotation of the starter shaft in a direction opposite the starting direction. At least one dog is interconnected with the starter shaft to engage the at least one cup in response to rotation of the starter shaft in the starting direction to thereby causes rotation of the crankshaft in the starting direction.

摘要： The automatic enrichment mechanism for an internal combustion engine is thermally-responsive and may also be centrifugally-responsive. The invention increases engine startability and minimizes stumbling and stalling of the engine during engine warmup. The thermally-responsive mechanism allows an additional reverse gas flow through the intake manifold to thereby increase the fuel discharged by the carburetor fuel nozzle. In several embodiments, the thermally-responsive mechanism, at low engine temperatures, causes a blocking or retaining member to keep an auxiliary cam member engaged with the cam follower of the valve assembly. As a result, the intake valve is partially unseated at low engine temperatures and a portion of the air/fuel mixture is fed back to the intake manifold. In these embodiments, when the engine temperature reaches a predetermined level, the thermally-responsive mechanism allows the auxiliary cam member to disengage from the cam follower in response to centrifugal force on the flyweights. In other embodiments, the thermally-responsive device allows crankcase gases to be fed to the intake manifold downstream of the fuel nozzle, causing a reverse flow of gas through the carburetor. The thermally-responsive member may be made from a thermal actuating polymer, commercial wax, bimetallic material, or from a nickel-titanium alloy which contracts at a predetermined engine temperature.
摘要翻译： 内燃机的自动浓缩机构是热响应的，也可以是离心式响应的。 本发明增加了发动机起动性，并且在发动机预热期间最大限度地减少了发动机的绊倒和失速。 热响应机构允许额外的反向气体流过进气歧管，从而增加由化油器燃料喷嘴排出的燃料。 在几个实施例中，在低发动机温度下，热响应机构使得阻塞或保持构件保持辅助凸轮构件与阀组件的凸轮从动件接合。 结果，在低发动机温度下进气阀部分地脱离，并且空气/燃料混合物的一部分被反馈到进气歧管。 在这些实施例中，当发动机温度达到预定水平时，热响应机构允许辅助凸轮构件响应于飞轮上的离心力而从凸轮从动件脱离。 在其他实施例中，热响应装置允许曲轴箱气体被供给到燃料喷嘴下游的进气歧管，导致气体通过化油器的反向流动。 热响应构件可以由热致动聚合物，商业蜡，双金属材料或在预定发动机温度下收缩的镍 - 钛合金制成。

摘要： The low cost speed governor is used to provide stable device speed over a wide range of selected reference speeds and loads. The speed governor includes a means for changing the pulse width of a pulsed reference signal as a function of the selected reference speed and the load applied to the device. Operational stability is achieved at low reference speeds by automatically increasing the speed droop as the selected reference speed is lowered and as the applied load is increased. Overall governor cost is reduced by an arrangement that uses the same potentiometer to both vary the selected reference speed and to automatically change the speed droop.

摘要： A speed controller for a DC motor minimizes speed droop and load droop through pulse width or frequency modulation. The controller provides an extra power increase upon engine starting or whenever a heavier load is temporarily encountered. The control circuit also has a current limiter, overload indicators, and a battery recharger. The controller is very inexpensive, primarily because all of the timing components are contained on a single integrated circuit timer chip such as a 556 timer. The controller contains other features, including a circuit for limiting the pulse width of the control signal from the pulse width modulator.
