Patent JP-S5630534-A (JP)
Title: Safety device for combustion system
Inventor: TANAKA EIICHI
IPC: F23N5/24
Filed: 1979-08-20
Abstract: PURPOSE:To protect the combustion apparatus against incomplete combustion that is possibly caused after long use of the apparatus, by providing shielding portions for restricting supply of the secondary air at a portion of burner flame and a sensor for detecting partial pressure of oxygen gas at a downstream portion of the burner flame on the outside of the flame where supply of the secondary air is restricted. CONSTITUTION:When a pilot burner 6 is ignited through manipulation of a cock or the like and flame F1 is formed by a burner 6, it is detected by a sensor 7 and a solenois valve 11 is opened and held in its open position by an electronic circuit 10. With subsequent ignition of the main burner 2 and formation of flame F2, temperature of a combustion sensor 9 disposed downwardly from fins 4 of a heat exchanger is raised and it is detected that fuel is combusted in a stable state. Here, if incomplete combustion of fuel is caused subsequently due to lack of air or by other reasons, flame F3 restricted of the secondary air by shielding portions 8 represents the state of incomplete combustion, and the solenoid valve 11 is closed by the output of the sensor 9 via the electronic circuit 10.

CONSTITUTION:When an excitation coil 16 is excited while a ring-shaped yoke 14 is rotated by an engine in a magnetic-powder type electromagnetic clutch, magnetic powder is filled up in a gap 32 between the opposite frictional surfaces 18 and 30 of the yoke 14 and a rotor 28, and by a frictional force among the particles of the magnetic powder and the electromagnetic coupling force thereof, the rotation of the yoke 14 is transmitted to the rotor 28. In this constitution, a plurality of slanting grooves 62 extending from both ends in the width direction of the outside frictional surface 30 of the rotor 28 toward the central part thereof are formed on the surface. These slanting grooves 62 are formed aslant at an angle theta to the direction toward the direction B of the mutual transfer vector of the inside frictional surface 18 in relation to the outside frictional surface 30. In addition, a circular groove 64 is formed in the center in the width direction of the outside frictional surface 30.
