Patent JP-H04332697-A (JP)
Title: Writing utensil
Inventor: HORI JIRO
IPC: B43K8/02
Filed: 1991-05-08
Abstract: PURPOSE:To stabilize the supply amount of ink, in a writing utensil such as a white market, by making the receding stroke of a slide plug due to a pump mechanism larger than the width of the elastomer seal provided to the outer peripheral part of the slide plug when standard equal pressure is applied to a pen body. CONSTITUTION:When writing pressure is applied to a felt tip 4, the felt tip 4 recedes and the piston body 7 of a pump mechanism 5 is deformed to pressurize the ink in an ink chamber 2. At this time, a slide plug 9 recedes but an ink film is not bonded to the inner peripheral surface of the ink chamber 2 on the side of a tail plug 11 from a seal part 10 and the slide plug 9 slides in a direct contact state. Therefore, the pressure in the ink chamber 2 becomes relatively high corresponding to the slide resistance at the receding time of the slide plug 9 and ink is sent to the felt tip 4 in the amount corresponding to the amount of the ink consumed in one stroke of writing. The receding quantity of the slide plug 9 exceeds the seal width of the seal part. Therefore, the part where the seal part 10 is in a close contact state before the receding of the slide plug 9 of the inner peripheral surface of the ink chamber 2 is wetted with ink.

Title: Relief valve
Inventor: NAKAZATO HIDEKAZU
IPC: F16K17/10
Filed: 1979-08-13
Abstract: PURPOSE: To obtain the direct-acting type relief valve with a stable reliefing pressure, by providing an adjustable gap in front side of a valve body, allowing this gap to produce the secondary pressure and applying this pressure onto a flange surface of the valve body to minimize an override value.  
     CONSTITUTION: An outer circumference of the flange 22 of a poppet-type valve member 16 of the relief valve is provided with a tapered surface 23, an inner circumferential surface of an end of a sleeve 12 on the opposite wall surface is provided with a tapered surface 25, and a gap 26 is provided between them in a conical shape. When the valve 12 starts opening, the gap 26 squeezes an oil flow to produce the secondary pressure in the secondary pressure chamber 24 on the bottom of the flange, and this pressure acts on the bottom surface of the flange 22 to push open the valve member 16 more smoothly. For this reason, an override value becomes small. Further, if the width of the gap 26 is changed by making screw adjustment of the sleeve 12 from outside, the secondary pressure value is adjusted, and it becomes possible to be set to an appropriate value by flow rate and full flow set pressure, and therefore, the reliefing pressure becomes stabilized.
