ABSTRACT:
A latchbolt assembly having a carrier with a solenoid operator mounted on the carrier is slidably received in a base or mounting cap with an annular groove formed in the carrier with a projection formed in the groove at a vertically downward location. A split ring is received in the groove with the projection orienting the gaps in the split ring and the split ring is compressed radially for sealing between the carrier and a base. A latchbolt is slidably received in the carrier and is connected to the solenoid armature for movement to the unlocking position upon energization of the solenoid. A cable extends through the housing and armature and is connected to the latchbolt for manual retraction by the user pulling on the cable. The latchbolt assembly is particularly suitable for motor vehicle fuel filler door latching applications.
