摘要： PURPOSE:To prevent the production of noises and the abrasion of the side-sealing material in a vane-type air pump to supply the secondary air for the purification of the engine exhaust gas by making the air-shutting up starting line bysymmetric, and providing a buffer chamber directly before the starting line. CONSTITUTION:In order to make the position where the air-shutting up is started bysymmetric with respect to the center of a cylinder 6, an air-shutting up starting line 50 is formed in parallel with the axis of the cylinder 6. A buffer chamber 73 provided directly before the starting line 50 permits fluid to be once shut up when a vane 10 passes a lip 72. When the vane 10 reaches the buffer chamber 73 a portion of the fluid escapes to a suction chamber 2, and so the fullscale shutting up is started when the vane 10 has reached the starting line 50. This prevents the production of noises due to a sudden air-shutting up. In addition, since the air-shutting up is successively performed bysymmetrically with respect to the vane 10, the abrasion of the side-sealing material due to the load axially displacing the vane 10 can be prevented.

摘要： PURPOSE:To prevent generation of thrust force due to differential pressure between pressures on left and right ends of vanes for reducing wear at the side portion of a cylinder by shaping a line of starting to enclose air symmetrically left and right with respect to the middle of a cylinder. CONSTITUTION:A line 50 of starting to enclose air is formed symmetrically left and right with respect to the middle of a cylinder 6. Thus, air begines to be enclosed from an end of a vane 10 with same rate symmetrically left and right and does not communicate to a suction chamber 2 when the vane 10 comes to a middle point (a). In this time, enclosed fluid is discharged from a discharge pipe 3 while the vane 10' reaches a discharge starting line 60 in a discharge chamber 4. Thus, since air is enclosed symmetrically left and right, generation of thrust force due to the differential pressure between pressures to both left and right ends of the vane can be prevented to reduce wear of side portion of the cylinder 6.

摘要： PURPOSE:To obtain the titled filter with good filterability and high reliability by forming a filter member in such a manner that a continuous recessed and protruded shape is provided in the flowing direction of a fluid and pleats are formed on the filter surface thereof concentrically. CONSTITUTION:A filter member 1 has a continuous recessed and protruded shape toward the flowing direction of a fluid and said shape is integrally molded in an almost concentrical circle form to the right angle direction against the flowing direction of the fluid. At the same time, pleats 11 are formed over the entire surface of a filter surface and, as the whole, molded in a concentrical pleat form. In this filter member, the fluid containing fine particles is flowed into the filter member 1 through a punching metal 3b and, after fine particles are removed, the purified fluid is flowed out through a punching metal 3a. As the result, the filter has a wide filter surface and the fluid is uniformly passed through the filter surface as well as pressure loss due to passing resistance is reduced and said filter has good collecting efficiency, excellent durability and high reliability.

摘要： PURPOSE:To minimize leak of gas from a cleaning device for fine particle contained in exhaust gas, by providing an exhaust-gas-fine-particle-capturing unit member with an outside covering made of a material having a larger ventilation resistance, and also by providing an annular seal between the outside covering and a casing. CONSTITUTION:Exhaust gas containing fine particles goes from an intake 17 of a cleaning device into a fine-particle-capturing material 10 made of ceramic. While the gas in the fine-particle-capturing material 10 is trying to leak out from the outside circumference, since it is enclosed by the material having a larger ventilation resistance, it is not allowed to leak out from the outside circumferencial area in any case. And, although the gas at the intake 17 is trying to leak out through a gap between the fine-particle-capturing material 10 and a casing 12, as an annular elastic seal 28 is pressed into the gap, the gas is prevented from leaking out. Thus cleaned exhaust gas is then discharged from an exit 19 to outside.

摘要： PURPOSE: To reduce the amount of discharge of unburned hydrocarbon at the time of ignition and extinction of fire through a comparatively small-sized device by a method wherein a fuel is vaporized after it is mixed with heated combustion air.
CONSTITUTION: Air supplied from a combustion air supply device comprising a pump or the like flows into the liquid fuel combustion apparatus from an air inlet of the latter. Then, the air passes through an electrical heater block 2 to be heated up to a temperature between about 200 and 300°C and flows into a mixing chamber 4 via a communication hole 3. On the other hand the fuel supplied from a liquid fuel supply device flows into the combustion apparatus through a pipe 5 and is injected into the mixing chamber 4 through a nozzle 5a. As a result, the fuel is subjected to a high speed stream of the heated combustion air so that the amount of discharge of the unburned hydrocarbon at the time of ignition and extinction of fire can be reduced.

摘要： PURPOSE:To heighten the efficiency of heating in a cleaner comprising a carbon particle collector means and a heating means for cleaning up carbon particles by burning them, by keeping exhaust gas from flowing to the coolector means at the time of heating by the heating means. CONSTITUTION:Exhaust gas containing carbon particles is conducted from an engine into the body 1 of a cleaner through an exhaust manifold. After the carbon particles are collected by a fillter member 2, the exhaust gas is discharged rearward. The pressure difference between the front and rear of the filter member 2 increases as the quantity of the carbon particles collected by the member 2 augments. When the pressure difference reaches a predetermined level, a solenoid valve 16, a glow plug 11, a fuel pump 7, an air pump 10 and solenoid valves 6, 9 are supplied with electric power by a control circuit 14 in accordance with the output of a pressure difference detector 13. As a result, the exhaust gas is discharged through a bypass 15, and a flame is produced by a burner 5 to burn up the carbon particles in the filter member 2.
