Title: Air bleeder for carburetor of internal combustion engine
Inventor: KAWADA MASAKATSU
IPC: F02M7/24
Filed: 1978-12-05
Abstract: PURPOSE: To expand an expanding chambers by introducing bleed air for preventing the attachment of the impurities contained therein to the air measuring portion of an air bleeder.  
     CONSTITUTION: An expanding chamber 11 for slow air bleed and an expanding chamber 12 for slow economizer air bleed are formed inside the wall 10 of the air suction passage of a choke chamber member 1. Bleed air is introduced into the expanding chamber 12 through an air suction passage and an air intake passage 14 to expand the expanding chamber 12 and to run against the side face of an economizer air bleed pipe 19 and the wall of the expanding chamber 12. Then, the pulsation of bleed air weckens, and the impurities contained in bleed air are separated to fall onto the bottom of the expanding chamber 12 and removed. The impurites therefore become difficult to attach to the air jet 21 thereof.

Filed: 1977-12-14
Abstract: PURPOSE: To enable boiled water to be heat-insulated properly and safely by directly controlling the temperature of boiled water by the use of a temperature controller constituted by combining an automatic return type disc thermostat and manual return type rapid thermostat.  
     CONSTITUTION: When the temperature of the liquid to be heated by a heater 10 is low, an automatic return type disc thermostat 8 and a heat-insulating thermostat 9 are closed, and the contact 5 of an I-shaped movable contact plate 2 is connected to the contact 6 of a fixed contact plate 4, and a heater 10 is brought to conduction. When the temperature of the heated liquid comes close to the boiling water temperature, the thermostats 9 and 8 described above are opened in order. Accordingly, an L type bimetal 1 is brought to conduction, and due to the bending of said bimetal, the contacts 5 and 6 described above are separated. Thus, when the temperature of the heated liquid lowers for example to 40 - 50°C, the thermostat 9 described above is closed, and after that, the temperature of the heated liquid is maintained at a fixed temperature for example at 40 - 50°C.
