Title: Magnetic joint driving type pump
Inventor: KODERA MASAYUKI
IPC: F04D13/02
Filed: 1982-07-02
Abstract: PURPOSE:To prevent the disordering phenomenon of the magnetic joint during operation by a method wherein the attracting forces of both magnets are strengthened and a distance between both magnetic boards is reduced to make the transmitting torque of both magnetic boards sufficient at all times. CONSTITUTION:When the driving magnetic board 6 is rotated by a motor 8, the follower magnetic board 4 is rotated through the joint, accordingly, an impeller 3 is also rotated and the pump is operated. The impeller 3 receives a thrust toward a suction port 12 side as the pump is operated, however, the attacting force between both magnetic boards 4, 6 is made stronger than the thrust and the impeller 3 will never be shifted toward the suction port 12 side. Accordingly, the distance between both magnetic boards will never be increased and the transmitting torque becomes sufficient thereby eliminating the disordering phenomenon of the magnetic joint.

IPC: F02M25/08
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent evaporated fuel from discharging from a fuel tank to outside air when a filler cap is opened at the time of supplying oil by providing a control means controlling the opening of a control valve so that internal pressure of the fuel tank may be negative pressure at the time of operating and stopping an internal combustion engine. SOLUTION: The temperature of fuel within a fuel tank 9 is detected by a Tg sensor 16 during the operation of an engine 1, and next, tank internal pressure of the fuel tank 9 is detected by a Pt sensor 15. Next, a target pressure value within the fuel tank 9 is calculated by an ECU 5. Next, a difference of tank internal pressure and the target pressure value is calculated and the opening of the control valve 30 is controlled so that the difference may be zero. When the engine 1 is stopped, the control valve 30 is closed to hold negative pressure within the fuel tank 9 controlled by the target pressure value. By holding the inside of the fuel tank 9 to negative pressure in this way, evaporation fuel within the fuel tank 9 is prevented from discharging to the outside air when a filler cap 11 is opened to supply oil.
