Pressure supply system for providing positioning elements with differing pressures - has controllable compressor connected to elements via feed line, pressure sensor and control switches

摘要

A pressure supply system for supplying at least two positioning elements (5,6) with different operating pressures which are both connected to a controllable pressure generator (2) via a feed line. The elements (5,6) both have a positioning member. They are separate and independently controllable. The first element (5) performs its function as part of a central locking system at a first pressure level. The second element (6) operates at a second level. The system includes a generator (2) which is controllable by at least one pressure sensor (DS) for generating different pressure levels. This is alternately actuable by a control switch (7) associated with the central locking system (ZVA) to commonly operate several similar elements with low levels. The second element (6) is part of a door lock assist device (TSH). The generator (2) is actuable by a second switch (8) to operate at a low pressure level. USE/ADVANTAGE - Esp. for use in motor vehicles, e.g. as common pneumatic feed system for central locking system and door lock whose elements operate at different pressure levels.
