摘要: Disclosed is an internal combustion engine comprising a main chamber and an auxiliary chamber which are interconnected with each other via a connecting passage. An annular raised portion is formed on the inner wall of the auxiliary chamber, and the auxiliary chamber is divided into a first auxiliary chamber and a second auxiliary chamber by the annular raised portion. The connecting passage is tangentially connected to the inner wall of the second auxiliary chamber. The nozzle of a fuel injector is disposed in the auxiliary chamber and is directed to the recess which is formed in the second auxiliary chamber beneath the annular raised portion at a position located opposite to the inner wall to which the connecting passage is tangentially connected with respect to the axis of the auxiliary chamber. The spark gap of a spark plug is located in the recess of the second auxiliary chamber. The connecting passage has an approximately elliptical cross-section which has a major axis and a minor axis. A ratio of the length of said minor axis to the length of the major axis is in the range of 0.4 through 0.6. An angle between the axis of the connecting passage and a plane defined by the flat top surface of the piston is in the range of 25 through 45.degree.. An angle between the axis of the connecting passage and the axis of the auxiliary chamber is in the range of 30 through 50.degree.. A ratio of the cross-sectional area of the connecting passage to the volume of the auxiliary chamber is in the range of 0.05 through 0.1 cm.sup.-1. The sum of the volumes of the auxiliary chamber and the connecting passage is more than 80 percent of the sum of the volumes of the auxiliary chamber, the connecting passage and the main chamber when said piston reaches the top dead center.

摘要: A roll type huller including a housing, a pair of hulling rolls parallelly spaced apart within the housing, a main shaft carrying one of the rolls and supported by the housing rotatably about a fixed axis, and a counter shaft carrying the other roll and supported near the free end of an arm mounted at the base by a pivot which is spaced from, and parallel with, the fixed axis, so that the counter shaft can move toward and away from the main shaft while maintaining the parallelism. The pivot is supported by the housing in a relative position opposite to the roll-carrying portion of the counter shaft. The location of the pivot may be inside the housing beneath the counter shaft or outside of the housing above the shaft or elsewhere provided the aforesaid relationship with the shaft is maintained.

摘要: A carburetor utilizing an acceleration pump, acting in conjunction with the throttle valve, to supply fuel through an injection channel to the fuel-air mixture chamber. A fuel accumulator contains a diaphragm under bias forming a diaphragm chamber of predetermined volume connected to the injection channel by a branch channel, a portion of the fuel supplied by the acceleration pump being diverted to the diaphragm chamber against the bias. The diverted fuel is fed to the fuel-air mixture chamber when the bias exceeds the pressure from the pump and the proportion of fuel diverted is controlled by the relative sizes of the open areas in restrictors positioned in the outlet of the injection channel into the fuel-air mixture chamber and of the branch channel into the diaphragm chamber, the strength of the bias and the maximum deformation of the diaphragm being adjustable.
