摘要： PURPOSE:To secure supercharging effect with a simple structure by enabling a pump operation by means of up-down of a piston, and pressure supplying new air sucked in a crank case via a first valve from a first intake passage, to a combustion chamber via a second valve and a second intake passage. CONSTITUTION:When a piston 5 is raised toward a top dead center during an exhaust stroke of an internal combustion engine E, an exhaust valve 13 is opened to exhaust combustion gas in a cylinder 6 from an exhaust port 11. The inside of a crank case 3 is at negative pressure by rising of the piston 5, and a first valve 29 is opened and a second valve 36 is closed. New air generated in a carburetor 28 is then sucked into the case via a first intake passage 27. During the intake stroke, when the piston 5 is lowered toward a bottom dead center and pressure inside the case 3 is increased, the valve 29 is closed and the valve 36 is opened. New air sucked into the case 3 in the exhaust stroke is pressure-supplied into the cylinder 6 via an intake port 10 so as to improve supercharging effect.

摘要： PURPOSE:To efficiently introduce fresh air into a crank case by way of positively controlling opening and closing operation of a lead valve by carrying out opening valve control of the lead valve by piezoelectric element. CONSTITUTION:A lead valve 14 has a valve body 15 provided with two pieces of rectangle valve holes 15a. A valve body 16 formed in a plate and a valve stopper 17 to regulate the opening valve position of the valve body 16 are jointly fastened with a bolt 18 on this valve body 15. And the valve body 16 is formed in one body with a bimorph type piezoelectric element and its free edge is divided into two branches and faces against the valve holes 15a. Then, a controller E controls the flow of current to the valve body 16 on the basis of the arithmetic result of detection signals from a pressure differential detection means 20 and a phase detection means 33, so that the lead valve 14 is positively opened by the deformation effect of the piezoelectric element. Consequently, as it is obviated to open the lead valve 14 against its elasticity, the introduction of fresh air from an air inlet pipe 13 to a crank case 3 is effectively carried out.

摘要： PURPOSE:To perform valve timing adjustment easily by rotating a rocking central part of a rocker arm in centering on a turning central part of a cam, and installing a rockable guide member between a rocker arm tip and a valve stem. CONSTITUTION:A pivot receiving member 16 of a rocker arm 13 is connected to a rockable lever 20 in centering on a turning central part B of cams 11, 12, and a rocking central part A of the rocker arm 13 in centering on the turning central part B of these cams 11 and 12. A rockable guide member 26 is installed between a tip of the rocker arm 13 and a valve stem 3A. Then, valve timing is adjusted by rotating the lever 20. With this constitution, since adjustment is mechanically and dynamically performed without any strain, it can be done easily.

摘要： PURPOSE:To aim at improvement of the performance of an engine by dividing an exhaust port into a plurality of ports, and then providing one port with a check valve and the other port with a valve which is caused to open at the time of a high load. CONSTITUTION:An exhaust port 15 is divided into a plurality of ports 151, 152. On at least either one of the ports 151, 152, in this case, on one port 151, is provided a check valve 18, which only permits the flow of exhaust from a cylinder bore 5 to an exhaust pipe 17. On the other port 152 is provided a valve 20 which is controlled to open at the time of a high load. Thereby, the back flow of exhaust gas and the blow-by of the fuel-air mixture can be de creased, and the performance can also be improved.

摘要： PURPOSE:To keep contact pressure between each vane and a housing constant all the time as well as to secure a stable sealing action, by engaging each vane with the cam surface formed in a similar figure with an inner circumferential surface of the housing, and thereby controlling a projection quantity from a rotor of each vane. CONSTITUTION:An internal combustion engine is provided with a rotor 2 and a housing 3 having an inner circumferential surface 3a, where this rotor 2 is housed free of rotation, and being curved so as to contact or separate alternately to or from an outer circumferential surface 2a of the rotor 2, and an inner side 3b to be opposed to a side face of the rotor 2. In addition, it is provided with plural vanes 4 being attached to the rotor 2 free of slide motion along the radial direction and forming plural airtight chambers A partitively between the outer circumferential surface 2a of the rotor 2 and these inner surface 3a and 3b of the housing. In the case, at the inner side 3b of the housing 3, there is formed with a cam surface of a similar form with the innercircumferential surface 3a. And, an engaging part 4a to be slidingly contacted with the cam surface is formed in the vane 4.

摘要： PURPOSE:To prevent the dust deposited on the bottom of a tank from flowing into a hydraulic system, by installing a hole, interconnecting a master cylinder and a reservoir tank with each other, in a bottom part of the reservoir tank as well as installing an annular barrier part surrounding this interconnecting hole. CONSTITUTION:A barrier part 22 is projectingly installed and locked to the bottom surface of a reservoir tank 2, and this barrier part 22 forms a continued fence wall surrounding a relief support 7 and a supply support 8 annularly. An upper surface of the barrier part 222 has a step 23, and height H2 of a part 22 adjacent to the supply support 8 is relatively high but height H1 of a part 221 adjacent to the relief support 7 is relatively low, while a blowup preventing plate 9 is attached to the part 222 and kept up. With this constitution, a hydraulic fluid is blocked by the barrier part so that a sort of the dust deposited on the tank bottom is prevented from flowing into a braking operation system.
