Abstract:
A shock absorber device for use in mooring and towing applications, said device comprising:a housing;a one piece, unitary anchor member disposed in said housing and comprising a rod including an eyelet at one end thereof for attachment to a shackle and a plurality of laterally extending flange members spaced along the length of said rod and received in respective cavities in said housing;a one piece, unitary piston member comprising a rod including a flange at one end thereof, and an eyelet at a second, opposite end for attachment to a shackle, said piston member being mounted in said housing so as to enable rotation of the piston member about the axis of said rod of the piston member; anda coil spring surrounding a portion of said rod of said piston member, said piston member and said coil spring being received in a further cavity in said housing such that a first end of said coil spring abuts said flange of said piston member and a second, opposite end of said coil spring abuts an inwardly facing end wall of said further cavity so that a pulling force of sufficient magnitude exerted on said rod will cause compression of said coil spring by said flange of said piston member to produce dampening of the pulling force.
