Title: Pressure control valve unit and automatic blood pressure gauge
Inventor: YAMAMOTO MASAMI
IPC: F16K31/06
Filed: 2000-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a pressure control valve unit used for a blood pressure gauge or the like, which reduces the number of part items and improves accuracy of the valve. SOLUTION: When this valve is closed, energizing a coil 3 causes a magnetic force to occur, thereby causing a slider 4 to be moved leftward. A packing 5 is pressed by the slider 4 and hence closes a through hole 1B. To open the valve, the electric current passing through the coil 2 is shut off, thereby causing the slider 4 to be returned rightward. Accordingly, the packing 5 is returned to its original position due to its own resiliency to open the through hole 1B.
