摘要： Provided is a sealing device that increases the lubricity of seal surfaces, prevents leakage of sealed fluids, and prevents excessive heat generation and excessive friction at seal surfaces. Said sealing device, which is of the type that seals a fluid trying to leak from the outer periphery of a sealing surface towards the inner periphery thereof, forms at least two dimples in a circumferential direction in each of a plurality of rows arranged in a radial direction on a sealing surface of a stationary-side sealing element or a rotating-side sealing element. Each dimple is tilted by a dimple angle ? between 0 DEG and 90 DEG , exclusive, such that the tip of that dimple in the direction of rotation is tilted toward the inner periphery side. In each of the plurality of rows of dimples, land areas are formed in the circumferential direction between the proximate tips of adjacent dimples. For each of the plurality of rows of dimples, if a circle is drawn through the centers of the dimples in that row, let L1 be the distance along the circle from the point the circle enters a dimple to the point the circle leaves that dimple, and let L2 be the length, along the circle, of the land areas between dimples. The dimples are characterized by being arranged such that the gap ratio L1/L2 is between 0.001 and 0.1, inclusive.

摘要： [Object] In view of a perfect seal being less necessary for a contaminant seal than for a fluid seal, it is an object of the present invention to use a seal ring having a seal part configured so that a contact area of the seal part is reduced and the seal part will not be compromised under pressure of a sealed fluid, whereby a contaminant-sealing device that takes up less space, and that operates with less friction, is provided. [Means for solving the problems] A contaminant-sealing device according to the present invention is characterized in that , in a sealing device comprising a rotating or reciprocatingly moving seal ring attached to one of two mutually opposed members and slidably placed in intimate contact with the other member, the seal ring has a cross-sectional shape that is quadrilateral and has a taper so that a surface of a sliding part is lower towards a high-pressure side and higher towards a low-pressure side, [the seal ring] being disposed so that a fluid body on the high-pressure side acts on the tapered part.

摘要： Provided is a solenoid valve wherein control characteristics are prevented from deteriorating due to changes of magnetic characteristics of a magnetic circuit when a center post is contaminated, and the desired control characteristics are maintained for a long period of time. In the solenoid valve, a nonmagnetic layer (41) is formed on the surface of a center post (40) by electroless nickel-phosphorous plating or composite electroless nickel-phosphorous plating containing PTFE. Thus, contamination of the center post (40) is remarkably suppressed, the characteristics of the magnetic circuit for moving the plunger (30) by magnetic attraction are prevented from changing due to changes of magnetic permeability between the plunger (30) and the center post (40), the plunger (30) and a valve element (55) integrated with the plunger are suitably moved corresponding to a current applied to a coil (20), and the valve is opened/closed.
