Abstract
A valve device includes: a valve member that controls flow of a fluid, and a body that has a valve insertion hole in which the valve member is inserted, and whose inner surface is cylindrically formed, and into which the fluid flows, and a lead-in passage that has an opening in the inner surface of the valve insertion hole, and that causes the fluid to flow into the valve insertion hole. A line representing the direction of extension of the lead-in passage is tilted from a line normal to the inner surface of the valve insertion hole at a position of the opening of the lead-in passage, in a view in the axis direction of the valve insertion hole.
Claims9
A valve device comprising:
- a valve body composed primarily of aluminum and comprising a cylindrical valve insertion hole having a central axis;
- a lead-in passage forming an opening in the cylindrical surface of the valve insertion hole, whereby a fluid can flow from the lead-in passage into the valve insertion hole, wherein at least a portion of the lead-in passage adjacent the opening in the cylindrical surface of the valve insertion hole is oriented such that the direction of elongation of the lead-in passage at the opening is tilted with respect to a normal line to the inner surface of the valve insertion hole at a position of the opening of the lead-in passage, in a view in a direction of the central axis of the valve insertion hole;
- and
- a valve member provided in said valve insertion hole, that is selectably engageable with a valve seat and separable therefrom to selectively form a clearance, to thereby control flow of the fluid past the valve member,
- wherein the valve device is configured such that the fluid flowing from the valve insertion hole to the clearance is prevented from flowing circumferentially about the central axis.
