ABSTRACT:
Vapor guard systems which prevent vapors from reaching a servomotor from a power source for the servomotor. One embodiment uses a control valve which directs such vapors to a vapor trap filter under conditions where vapor flow may be toward the servomotor, and operates to permit purging of the vapor trap filter when there is flow only away from the servomotor. Another embodiment uses an in-line vapor trap filter and a vapor trap canister, normally used to trap fuel vapors from a vehicle fuel tank, to trap fuel vapors from the power source. Both the in-line vapor trap filter and the canister are purged of adsorber vapors where the power source is operating.
