Fluidic latching system for motor vehicle doors - has electrically-driven pump with large lifting vol. and reduction gear

摘要

The latching system for locking mechanisms on doors and valves of motor vehicles contains an electrically-driven lifting cylinder pump operated by the over or under pressure. Each locking mechanism is fitted with a single chamber fluidic working element linked to the lifting cylinder pump via a single pipe system. The power supply to the drive of the pump is switched on by the key. The lifting volume of the pump is greater than the sum of the individual lifting volumes of the connected working elements of the locking mechanisms. There is a speed step-down gear between the pump drive and the lifting cylinder.
