Claims (6)
1. An apparatus for the multi-stage* hydraulic-mechanical braking of the forward movement of a displaceable barrel member of an automatic iring weapon, comprising a hydraulic brake incorporating a cylinder, a brake piston equipped with check valves arranged in said cylinder, a mechanical brake connected in series with the hydraulic brake, said mechanical brake being equipped with a set of springs, said check valves being opened during a first portion of the forward movement of the barrel member of the firing weapon, a displaceable ring member capable of moving between a working position and a rest position, said displaceable ring member being displaceable out of the working position by the piston into a rest position, stop means for limiting the stroke ©f the displaceable ring member, a spring member which strives to retain the displaceable ring member in its working position where said displaceable ring member closes the check valves of the brake piston as soon as it comes to bear during a second portion of the forward movement of the barrel member of the weapon against the brake piston, said set of springs being arranged in said cylinder, said displaceable ring member being located between the brake piston and the set of springs for transmitting the forces of the forward movement of the barrel member to the set of springs during a third portion of the forward movement of the barrel member past its starting position.
2. , The apparatus as defined in claim 1, wherein said brake piston possesses continuous substantially axially extending bores and a further spring-loaded ring member defining said, check valves, said further spring-loaded ring member forming a valve plate for said check valves, said displaeeable ring membe and said further spring-loaded ring member bearing against the axially extending bores of said brake piston.
3. The apparatus as defined in claim 1 , furthe including a sleeve member arranged between the inner wall of said cylinder and the brake piston, said sleeve member having a first slot through which a fluid medium can flow from one face of the brake piston to the other face thereo f said slot extending over the length of the stroke of the piston and becoming wider in the direction of the forward movement of the barrel member,
4. The apparatus as defined in claim 3, wherein said sleeve member possesses a sebond slot, said displaceable ring member having a cam extending into said second slot* the end of said second slot and the cam forming said stop means for limiting the stroke of the displaceable ring member in one direction.
5. The apparatus as defined in claim 3, wherein the forwardly extending end of the first slot which extends past the starting position of the brake piston is considerably narrower than the remaining portion of the first slot*
6. The apparatus as defined in claim 1, further including a sleeve arranged between the piston rod and the set of springs, said sleeve having a flange which in the starting position of the brake piston is ©lamped between the displaceable ring member and the set of springs* P. 0. Box 331 16 , Tel- A v i v Attorneys f o r A p p l i c a n t
