  • Accumulator and lubricant supply system
    Patent number: 11662060
    Abstract: An accumulator includes a tank body having a communication port that communicates the lubricant accommodating space capable of accommodating lubricant with the outside, the tank body extending around an axis, a piston that moves in the axial direction in the tank body to vary the size of the lubricant accommodating space, a spiral spring mechanism having a spiral spring, and a rotational force transmission member that converts a linear movement of the piston into a rotational force around the axis to transmit the converted rotational force. The rotational force transmission member converts a rotational movement due to a restoring force of the spiral spring into a force in the axial direction to move the piston in the axial direction.
    Type: Grant
