MICRO MOTION POPPET VALVE ASSEMBLY FOR DELIVERY OF INK WITH LARGE PIGMENT PARTICLES TO A WRITING NIB AND WRITING INSTRUMENT COMPRISING SAME |
摘要 |
A micro motion poppet valve for a writing instrument provides delivery of ink with large pigment particles to a porous writing nib with minimal nib movement and relatively light actuation forces. The micro motion poppet valve includes a nib connected to a valve stem, the valve stem being connected to a valve plug. A valve body is integrally formed with a biasing element, which biases the valve stem towards a closed position. When a user presses the nib against a writing surface the valve plug moves away from a raised valve seat located on the biasing element to allow ink to flow from an ink reservoir to the nib. |
