Automatic belt tensioning system

A belt tensioning system, comprising:

• a driven member, a driving member and a force transmitting device in force transmitting communication with both the driving member and the driven member;
• a moving member having at least a wall in fixed communication with the driven member and movable relative to the driving member;
• an adjustment mechanism comprising a rod, a restraining member and a biasing member;
• wherein the restraining member is threaded upon a portion of the rod, is positioned below the moving member and substantially opposes rotational movement of the rod;
• wherein the biasing member is positioned between the restraining member and the wall of the moving member such that a force is applied to the moving member;
• and
• wherein a substantially constant tension is applied to the force transmitting device.

A belt tensioning system, comprising:

• a plurality of driven members, a driving member and at least one force transmitting device in force transmitting communication with both the driving member and the plurality of driven members;
• a plurality of moving members, each having at least a wall, in fixed communication with the plurality of driven members and movable relative to respective driving members;
• an adjustment mechanism for each of the plurality of driven members each comprising a rod, a restraining member and a biasing member;
• wherein each restraining member is threaded upon a portion of its respective rod, each positioned below their respective moving member and each substantially opposes rotational movement of their respective rods;
• wherein the biasing members are positioned between each of the restraining members and the wall of each of their respective moving members such that a force is applied to each of the plurality of moving members;
• and
• wherein a substantially constant tension is applied to the at least one force transmitting device.

A belt tensioning system for use with a pressure washer assembly, comprising:

• a pressure washer, an engine, and a belt in force transmitting communication with both the pressure washer and the engine;
• a base portion in fixed communication with the pressure washer and longitudinally movable relative to the engine;
• an adjustment mechanism comprising a rod, a nut, an extension and a spring;
• wherein the nut is threaded upon a portion of the rod, is positioned below the pressure washer which has at least a wall and the extension opposes rotational movement of the nut;
• wherein the spring is positioned between the nut and the wall of the pressure washer such that a force is applied to the pressure washer;
• and
• wherein a substantially constant tension is applied to the belt.
