ABSTRACT:
An elastic support for a horizontally rotating washing machine or the like in which two spring support strut assemblies are disposed substantially in the middle of the machine and to either side of a vertical plane which includes the axis of rotation. Each of the spring strut assemblies is double-acting, i.e., it has an upper guide rod and a lower guide rod, each of which is surrounded by a compression spring. The top of the upper guide rod is attached to the washing machine housing and the bottom of the lower guide rod is attached to the base of the machine. The free ends of the guide rods move axially within a single guiding and damping casing which has internal passages for guiding the rods. The casing may consist of two or more parts and is so constructed that when the casing parts are clamped together with a variable force, the casing is deformed and a varying amount of radial pressure is applied by the walls of the passages to the surface of the guide rods, thereby causing a selectable amount of damping friction with respect to the axial motion of said guide rods.
