Did you know that Belleville washer is known also as a conical spring washer? It can be loaded along its axis either statically or dynamically and are used on different industries. Its purpose is to solve vibration, thermal expansion and relaxation problems. On marine engine’s rotocaps their purpose is to solve the vibration problems due valve’s continuous opening and closing and thermal expansion problems during engine running. Belleville washers can be found installed into anchor winches hydraulic brakes. They are installed as a washer stack spring and it’s purpose is to close the winch brake once the hydraulic pressure is released.

Did you know that the rotocap is a mechanical device which produces valve rotation by a small amount as the valve opens? The valve rotation is about 8 deg. When the unit is in good condition and rotation to a new position avoids deposits from being hammered into the seat and repositions the valve thus preventing local overheating. Frictional contact is provided through the springs to the valve cover via the beleville washer which contacts at point A and C. As the tappet force increases to open the valve, the belleville washer is collapsed thus removing frictional contact. Further increase in tappet force acts on the spring loaded ball bearings and the ramped slots tend to slide over the ball bearings. These slots are in the valve cover which is connected to the stem thus as the cover moves it rotates the valve. As the tappet force is removed when the valve closes the belleville washer restores frictional contact and prevents further rotation. Spring return back to original position ready for the next stroke.

Did you know that the air compressor unloader valve is a device used by air compressors to release the trapped air inside the compression chamber and the air bottle discharge line when the motor stops? This allows the compressor motor to start easier and without load. Otherwise, the load generated by entrapped air in the compression chamber will create a high initial torque that the motor may have difficulty to overcome. #chief_engineer_log #chiefengineer #lifeofmarineengineer #marineengineering #mechanicalengineer #mechanicalengineering #seafarerslife💯⚓️🚢 #seafarer #seamanlife #seamen #engineersatsea #electricalengineer #solas #ladyengineer #ship #ocean #sea #seamen_life #seamans #womanatsea #humansatsea #mechanicaleducation #navalarchitectureandmarineengineering #mechanicalengineeringstudent #womanseafarer #sealife #seamanship #seamanslife #seaman #aircompressor
