Continuously blockable arresting device

摘要

A continuously blockable arresting device includes a housing and a shaft having an end received in the housing and which may be externally acted upon causing rotation thereof. The housing has a fluid-filled working space and two subchambers which can be connected to the working space. The subchambers lie next to each other. First and second pistons are guided respectively in a displaceable manner in the subchambers and can be displaced therein by a swash plate. The shaft is connected to the swash plate for rotating the swash plate. Respective control devices of the subchambers include blocking valves for respectively connecting the subchambers to the working space and passage valves for respectively connecting the working space to the subchambers.
