Abstract
A locking unit for locking the movement of a piston which can be acted on with pressure of a fluid, the locking unit having the piston, an electromagnet, and at least one detent element. The detent element interacts with an armature or an armature rod of the electromagnet. The piston has at least one detent receptacle, and the piston can be secured by a retaining interaction of the detent element with the detent receptacle. The piston is adjustable between a retracted position and an extended position, and the piston can be designed at least in sections as a hollow part.
Claims18
A locking unit for locking a movement of a piston which can be acted on with pressure of a fluid, the locking unit comprising:
- the piston;
- an electromagnet;
- at least one detent element;
- a housing;
- and
- a pressure the housing is configured to form a me ing fluid channel which is fluidically c ecte d to the pressure chamber, wherein the housing has a cover whic ers the meandering fluid channel and has a fluid o pening ch opens into the me de a fluid channel,
- wherein the at least one detent element interacts with an armature or an armature rod of the electromagnet, wherein the piston has at least one detent receptacle, wherein the piston can be secured by a retaining interaction of the at least one detent element with the at least one detent receptacle, wherein the piston is adjustable between a retracted position and an extended position, wherein the piston is designed at least in sections as a hollow part.
A locking unit for locking a movement of a piston which can be acted on with pressure of a fluid, the locking unit comprising:
- the piston;
- an electromagnet;
- at least one detent element;
- a housing;
- a magnetic element connected to the piston;
- and
- at least one magnetic field sensor for sensing a magnetic field of the magnetic element,
- wherein the at least one magnetic field sensor is arranged on or in the housing,
- wherein the housing comprises a fluid opening, wherein the at least one magnetic field sensor is arranged in the fluid opening of the housing,
- wherein the at least one detent element interacts with an armature or an armature rod of the electromagnet, wherein the piston has at least one detent receptacle, wherein the piston can be secured by a retaining interaction of the at least one detent element with the at least one detent receptacle, wherein the piston is adjustable between a retracted position and an extended position, wherein the piston is designed at least in sections as a hollow part.
