Abstract:
1. A liquid separator for separating oil in compressed air systems, comprising: a separating element and a housing, wherein said housing comprises a lid and a cup, wherein said separating element is arranged seal-tightly within said housing and said housing is detachably connectable to a counterpart, wherein the housing is detachably and lockably connectable by a bayonet connection to said counterpart, wherein said bayonet connection is formed between said lid and said counterpart, wherein said bayonet connection is locked closed by an axial tension force acting between said lid and said counterpart, said axial tensioning force urging said lid and counterpart to axially separate, wherein said tension force urges said radially extending contours to lock into a rotational stop on said receiving geometries, said rotational stop preventing accidental rotation and opening of said bayonet connection, wherein said lid has an inlet for gas to be purified, an outlet for purified gas, and a liquid outlet for separated liquid, wherein said liquid outlet is arranged in a bottom area of the lid with respect to a direction of gravity, said liquid outlet communicating with a drain that is arranged in said counterpart, wherein said separating element is seal-tightly connected to said lid, wherein gas pressure within said housing provides at least a portion of said axial tension force.
