DETONATION TRANSMITTER Russian patent published in 2001 - IPC

FIELD: vibration tests of internal combustion engines, electron control systems of internal combustion engines. SUBSTANCE: detonation transmitter has base with flange confined in electric insulation case, piezoelement and inertial element pressed against piezoelement with the aid of spring and fixing member and mounted on base, aid protecting against effect of electric insulation case that embraces piezoelement, inertial element and spring, current collectors, electric insulation spacers and current leads-out connected to current collectors. Protecting aid is manufactured in the form of electric insulation adhesive coat which embraces fixing member in addition. Value of elasticity modulus of material of coat is less than value of elasticity modulus of electric insulation case. Electric insulation spacers and current collectors are made as one unit. EFFECT: increased structural stock by frequency properties, enhanced value of conversion factor and uniformity of amplitude-frequency characteristics, stability of above-mentioned characteristics in process of manufacture and operation, improved adaptability to manufacture. 1 cl, 3 dwg
