A device for switching and elastically locking the end positions of movable switch parts, in particular switch tongues of grooved rail switches, including an axially displaceable rod ( ) and a tube ( ) surrounding the rod, in which a spring ( ) encompassing the rod is braced against stops and locking members ( &prime;) capable of being displaced radially outwards are arranged, wherein the rod ( ) has axially spaced-apart control stops ( ) for a radially inward position of the locking members ( &prime;) and the tube ( ) has stops ( ) for the outward position of the locking members ( &prime;), wherein at least one ( ) of the control stops ( ) of the rod ( ) is displaceable relative to at least another one ( ) of the control stops ( ) in the axial direction of the rod ( ) and is capable of being fixed in the respective displaced position.

Device for adjusting and elastically locking moveable switch parts

In a device for displacing the movable parts of rail switches or crossings, in which a plurality of hydraulic cylinder piston units engaging in an offset manner in the longitudinal direction of the rails are each connected in series, at least one directional or seat valve ( ) capable of being adjusted in a pressure controlled manner is inserted in the duct ( ) that connects the hydraulic cylinder piston units ( to ) arranged in series, which directional or seat valve blocks the connection to the consecutive cylinder piston unit if a preset differential pressure is exceeded.

Device for displacing the moveable parts of rail switches or crossings

A device for locking the end positions of movable railway switch parts in which two parts axially displaceable relative to each other are displaced into a position coupled to each other for movement in at least one direction. The relatively displaceable parts, formed by a tube and a rod guided within the tube, are arranged at least partially within a stationary external tube. Locking elements comprising balls cooperate with the axially displaceable parts and the external tube and are displaceable radially into a lock position within a recess of the external tube. The balls are surrounded by a ring resiliently held in a position having an outer diameter smaller than, or equal to, the outer diameter of the axially displaceable tube retained in a peripheral groove of the tube. The balls are arranged in openings in the tube between the rod and the ring.

Device for locking end positions of mobile switch parts

In a connecting device for a switch actuator and/or a lock for movable parts of a railway switch or crossing, including a rod assembly, in particular a sliding rod or a locking rod articulately connected with the movable part, the movable part or the rod assembly, in particular the switch tongue (,), is rigidly connected with a strap (,) engaging from behind a pin (,) connected with the rod assembly or the movable part for transmitting tensile forces. Between the rod assembly and the strap (,) or the movable part is arranged at least one elastic compression element, which is compressible by the rod assembly in the abutment position of the movable part on a rigid rail part, the strap (,) being displaceable out of abutment on the pin (,).
