摘要： A vortex-flow blower device includes an impeller having a plurality of fins, a blower housing that has a vortex flow chamber for accommodating the impeller and extends from a start point on a side of a the fluid inlet port to an end point on a side of a fluid discharge port along the plurality of fins, a partitioning portion that blocks a communication between the end point and the start point in the vortex flow chamber, and a thermal fuse that is provided in the blower housing. The thermal fuse can be fused by a temperature rise so as to discharge the fluid on the side of the fluid discharge port to an outside, or communicate with the side of the fluid discharge port to the side of the fluid inlet port in the vortex flow chamber when the thermal fuse is fused.

摘要： A self-opened type valve is opened by motor torque of an electric motor. Therefore, a diaphragm is not necessary for opening the valve, and downsizing of a valve drive apparatus for opening the valve is possible. Since the valve is assembled to the motor shaft of the electric air pump via a motion-direction conversion mechanism, an opening action of the valve can start in a short time after a rotational action of the impeller of the electric air pump starts, so that control responsiveness is improved. At a rotation stop of the impeller of the electric air pump, the valve can be maintained in a fully closed condition by an urging force of the coil spring, thereby preventing exhaust gases or condensed water from entering into an inside of the electric air pump.

摘要： In an air supply pump, having an electric motor and a blower driven by the electric motor, the blower has an impeller having multiple blades for compressing and pumping out the air. A value (F) obtained by a formula (F=N×S) is made to be higher than the audible frequency band to the human beings, wherein “N” means number of blades of the impeller, and “S” means a number of rotation of the impeller for each second at a normal rotational speed. (“×” is a symbol for a mathematical multiplication.) The frequency (F=N×S) of fan noises at a primary peak appears at higher frequencies out of the audible frequency band, so that the noises audible to the human beings can be reduced.

摘要： A rotary blade molding method, a rotary blade molding die and a rotary blade molded thereby are disclosed. A cavity (79) for molding an impeller (31) is formed between a fixed-side die plate (59) and a movable-side die plate (75). The movable-side die plate (75) has a plurality of outer through holes (81) formed in spaced relation to each other in the peripheral direction on the inner peripheral surface of the cavity (79) and extending in the direction along which the fixed-side die plate (59) and the movable-side die plate (75) move away from or toward each other. Outer ejector pins (83) are removably inserted into the outer through holes (81), respectively. By changing the length of the outer ejector pins (83), the axial position of the forward end surface of each outer ejector pin (83) with respect to the inner peripheral surface of the cavity (79) is changed, so that the thickness of a molded product is changed thereby to adjust the balance of the impeller (31) around the axis thereof. As a result, the unbalance of the rotary blade can be adjusted by an inexpensive and simple method.

摘要： In the disclosed secondary air supply system, an on-off valve (13) is driven by the discharge pressure of an air pump (12). A diaphragm chamber (44) is arranged in the neighborhood of a discharge outlet (54), and a part of the discharge air flows directly into the diaphragm chamber (44). Thus, the on-off valve (13) is positively operated even at high places with low atmospheric pressure and has a fast open/close response. As an electromagnetic actuator is not used to drive the on-off valve (13), the voltage supplied to the air pump (12) (DC motor (29)) does not drop inconveniently, and at the same time, the cost is reduced. Further, the number of the lead wires (65) is reduced.

摘要： According to the present invention, the exhaust gas recirculation control apparatus includes a first switching valve for controlling communication between the positive pressure supplying source and the control valve. The first switching valve opens only when the control means increases and maintains the predetermined pressure supplied to the EGR valve, and under other conditions, the first switching valve closes, so that the positive pressure of the positive pressure supplying source can be utilized only when needed and the positive pressure accumulated inside the positive pressure supplying source can be prevented from leaking from the control valve. When an air compressor, which is mounted for a braking in a vehicle, is commonly used for the EGR valve as the positive pressure supplying source, air pressure of the brake system in the air compressor can be effectively used, a small-sized EGR apparatus being thereby manufactured.
