AUTOMATIC FUEL INJECTION ADVANCE COUPLING Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: automatic fuel injection advance coupling had driving and driven coupling members, centrifugal flyweights with pull-back springs and spring retainers placed between coupling members and connected with driving coupling member by means of pins. Pins secured in coupling member are arranged on lock pins fitted in inclined through slots made in flyweights at side of this coupling member. Flyweights are directly coupled with driven coupling member by means of straight projections made on flyweights at side of this coupling member, and straight slots provided in driven coupling member into which these projections get. Maximum travel of flyweights in radial direction is limited by spring retainers thrusting against each other. Length of retainers is chosen to provide required maximum turning of driven coupling member relative to driving one. EFFECT: simplified design, facilitated assembling, reduced time taken for assembling and cost of manufacture of couplings. 3 dwg
