Title: Discharge control device for fuel vapor
Inventor: MURACHI MIKIO
IPC: F02M25/08
Filed: 1979-06-04
Abstract: PURPOSE: To prevent fuel vapor from being discharged to the outside when the fuel is filled to a tank, by providing pressure reducing means for reducing the pressure in a fuel vapor adsorbing vessel as necessary when an internal combustion engine is stopped and allowing the fuel vapor when necessary to be attracted and adsorbed forcibly into the above described adsorbing vessel.  
     CONSTITUTION: When a cap 22 is set to a fuel filling port 14 of a fuel tank 10, a solenoid valve 34 closes a pipe line 32 and a three-way valve 38 allows an atmospheric link port 30b of a canister 30 to be linked to an inflow pipe 36 for elimination reacting air. Accordingly, if a fuel vapor pressure in the tank 10 is raised to the atmospheric pressure or more, a check valve 20 is opened to permit a canister 16 to perform the action of suppressing a discharge of the fuel vapor. While a hydrocarbon which has been adsorbed to the canisters 16, 30 is attracted to a suction line by the operation of an engine. On the other hand, if the cap 22 is removed for the fuel filling operation, the pipe line 32 is opened by the valve 34 and the atmospheric link port 30b is linked to a suction pump 40 by the three-way valve 38 to prevent the discharge of fuel vapor from the filling port 14.

Patent JP-S56165723-A (JP)
Title: Turbo-charger shaft sealing unit
Inventor: HIRABAYASHI YUUJI
IPC: F16J15/54
Filed: 1980-05-26
Abstract: PURPOSE: To eliminate the friction loss due to a sealing material by providing a drive mechanism such as a solenoid so that the sealing material can be pulled off from a mating ring under an operational condition where a compressor outlet pressure becomes greater than a lubricant oil pressure.  
     CONSTITUTION: A sealing material 27 is in an elastic contact under the force of a spring 28 with a mating ring 23 which is being fixed to a rotating shaft 20. The differential switch 30 responds to a pressure difference between outlet pressure 45 of a room B of a compressor 21 and a lubricant oil pressure 44 of a room A. Because the lubricant oil will not leak to the compressor side when a supercharger pressure is high in a high-speed and high-load area, a solenoid 29 gets excited via a differential switch 30 so as to pull the sealing material 27 off the contacting surface against the spring 28. Thus, the sealing material 27 gets distanced from the mating ring 23 for the friction loss to eventually become zero resulting in an enhanced turbo- charger efficiency.
