Abstract

Door lock comprises a housing, a plunger (3) linearly guided in the housing, and a hydraulic damping unit. The inner chamber of the housing is filled with a damping medium and is divided into two chambers. An overflow valve is arranged in the plunger for the passage of the damping medium. when the door leaf is opened. A valve body (18) can be guided into the plunger bore (14) and is sealed with the inner surface of the plunger bore using a seal (19). Preferred Features: The plunger bore has a unit for limiting the sliding movement of the valve body. The plunger bore has a recess. The valve body has locking tongues (20) which interact with the plunger bore in a locking manner.
