減圧弁
Document Type and Number:
Japanese Patent JP6717099
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure-reducing valve that can prevent a radial direction gap between a valve body and a valve hole from generating large deviation in a circumferential direction even if the valve body is inclined with respect to the valve hole in opening/closing the valve body.SOLUTION: In a pressure-reducing valve 11, a position contacting a high pressure chamber 22 is a first contact position P1, and a position contacting a low pressure chamber 23 is a second contact position P2 in the case where a valve body 24 tilts. In the case where the valve body 24 is coaxially arranged with a valve hole 21a, the high pressure chamber 22 and the low pressure chamber 23, a radial direction gap between the first contact position P1 and the high pressure chamber 22 is defined as C1, and a radial direction gap between the second contact position P2 and the low pressure chamber 23 is defined as C2. Further, in the case where a distance between the first contact position P1 and a reference point P0 is defined as L1, a distance between the second contact position P2 and the reference point P0 is defined as L2, and the valve body 24 is in a fully open state or a fully closed state, the reference point P0 which satisfies the relationship of formula (1) is set so as to be positioned within a range of a valve seat 21 in a thickness direction. (Formula 1) L1:L2=C1:C2...(1)SELECTED DRAWING: Figure 2
