Two conflicting functions of sealing and lubrication of sliding faces are achieved for a long time. The sliding face of a rotating-side seal ringis provided with dynamic pressure generation groovesconfigured to communicate with the circumferential edge on the inner peripheral side of the sliding face and not to communicate with the circumferential edge on the outer peripheral side. A springis provided on the back side of a stationary-side seal ringfor pressing the stationary-side seal ringagainst the sliding face of the rotating-side seal ring. A spring holderis provided between the back side of the stationary-side seal ringand the spring

Mechanical seal

The purpose of the present invention is to provide a mechanical seal whose axial dimension can be reduced without impairing sealing performance. In a mechanical seal including a rotating-side sealing ring; a stationary-side sealing ringprovided within a caseand sliding on the rotating-side sealing ring; a biasing memberfor biasing the stationary-side sealing ringto the rotating-side sealing ring; and an engagement meansfor restricting the rotational relative movement between the caseand the stationary-side sealing ring, the biasing memberis arranged radially outside the stationary-side sealing ring

A mechanical seal in which a rotary ring can be more reliably positioned. A rotary ring unitincludes: a sleevefixed to a rotary shaft; and a rotary ringof which a movement in an axial direction and a rotation with respect to the sleeveis restricted, a fixed ring unitincludes: a fixed ringconfigured to slide on an end surface of the rotary ring; and a bellowswhich presses the fixed ringtoward the rotary ring, and the sleeveis provided with a stopperwhich restricts a movement of the rotary ringtoward the fixed ring

In an exemplary embodiment, a sealing memberis provided between a rotating bodyrotating while whirling within an accommodating chamberpartitioned by a housing and a side wallof the accommodating chamberand has a sliding surface S sliding on the side wall, and the sliding surface S includes a first lubrication mechanismarranged on one side in the longitudinal direction, and a second lubrication mechanismarranged on the other side in the longitudinal direction and exhibiting lubrication performance in a sliding direction different from that of the first lubrication mechanism, thereby improving sealing performance of the sealing member.

Sealing member

An oil seal member is provided at an outside surface of a member performing whirling motion such as a rotary engine rotor. A sliding face of the oil seal member that slides relatively to a stationary-side member is provided with a step extending circumferentially, and has a relatively high surface formed on one radial side with respect to the step and a relatively low surface on the other radial side. The high surface is provided with pumping grooves to pump oil tending to leak from the high surface side into the low surface side, into the high surface side by sliding relatively to the stationary-side member.

The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having an excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and increases in internal resistance upon repeated charge/discharge cycles are suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by benzotriazole.

Nonaqueous electrolyte and nonaqueous secondary battery

The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and self-discharge during high-temperature storage is suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising 30 to 100 vol % of acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by pyridine.

In an embodiment, in a sliding component, a sliding face of a stationary-side seal ringhas a fluid circulation groovecommunicating with a high-pressure fluid side via an entrance portionand an exit portion. A rotating-side seal ringhas a larger outer diameter and a smaller inner diameter than the seal ring. A grooveinto which a claw is loosely fitted is provided on an outer periphery of the seal ring. A width of the grooveis smaller than a distance between the portionand thein the circumferential direction. WMR/WSR is set within a range of 0.75&#x3c;WMR/WSR&#x3c;1.4 (WMR is a face width between an inner diameter of the grooveand an inner diameterof the sliding face; WSR is a face width of the sliding face).
