摘要： A mechanical speed governor for internal combustion engines includes a centrifugal weight carrier and an arm means that extends through the top side of the upper engine housing. The arm means moves in response to movement by the centrifugal weight carrier to control the amount of fuel delivered for engine combustion. The governor arrangement avoids the oil seal and bell crank levers required in prior art devices.

摘要： In one embodiment, a device interface board is provided which includes a printed circuit board with a DUT interface structure, such as socket, associated with a DUT side of the printed circuit board. A high frequency connector and electronic component are mounted in a cavity formed in a back side of the printed circuit board. A signal via through the printed circuit board couples the high frequency connector and electronic component with the DUT interface structure. An encapsulating structure may be provided, which covers the cavity while allowing a cable to connect to the high frequency connector.

摘要： A four-stroke internal combustion engine is provided that is capable of use in many power tools, including those power tools subjected to tippable applications. There is provided within an engine housing an oil reservoir and a valve chamber which independently communicate with a crank chamber. A strategically placed divider and passageway, located within the engine housing, appropriately direct lubricant within the engine housing so that the internal cavity of the engine is lubricated during use in various operating attitudes, and so that the fluid flows to and is held in the proper chambers of the engine housing during storage. There is also provided a breather arrangement for an internal combustion engine which includes a cam shaft having a hollow passageway in communication with the crank chamber and the air intake system of the engine.
