Title:
PRESS MECHANISM AND PRESSURE-REDUCING VALVE HAVING THE SAME
Document Type and Number:
Japanese Patent JP2017204245
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a press mechanism capable of suppressing an abrasion accompanied with a slide of a piston and a pressure-reducing valve having the press mechanism.SOLUTION: A press mechanism 6 of a pressure-reducing valve includes: a bottomed cylindrical cylinder 51; a piston 52 slidably stored inside a cylinder 51; and a coil spring 53 arranged in a compressed state between a bottom part 62 of the cylinder 51 and the piston 52 and energizing the piston 52. Sit surfaces 82 and 84 on which end surfaces 81 and 83 of the coil spring 53 in the cylinder 51 and the piston 52 sit are in parallel with each other and formed inclined toward an orthogonal surface S orthogonal to an axial line L2 of the cylinder 51. The end surfaces 81 and 83 of the coil spring 53 are formed in a flat surface state orthogonal to the center axis L1. Each of inclined angles β and γ for the orthogonal flat surface S of the sit surfaces 82 and 84 is set so as to be equal to an orthogonal angle α between a resultant force Fc of the coil spring 53 and the center axis L1.SELECTED DRAWING: Figure 3
