244	Valve timing adjustable device	JP2003316580	2003-09-09	JP2005083264A	2005-03-31	KAKIHARA TOMONORI; MITSUOKA NAOCHIKA
PROBLEM TO BE SOLVED: To provide a valve timing adjustable device capable of enhancing workability at assembling of a chip seal without affecting the process at manufacturing of a plate spring and the chip seal. SOLUTION: The valve timing adjustable device is installed in a drive force transmitting system to transmit the rotation force to a camshaft equipped with a cam to open and close a valve. A hydraulic chamber to make relative revolution between a case at an input side for the camshaft and a rotor at an output side to the camshaft is formed between the case and the rotor. The case and the rotor generate the relative revolution by controlling the hydraulic pressure for the hydraulic chamber so as to change rotation phase of the camshaft, and change an opening and closing timing of the valve. Both the chip seal and the plate spring which are attached to the case or the rotor to seal the hydraulic chamber are made of a metal plate. The valve timing adjustable device is a metallic assembly which is previously and mutually assembled with the chip seal and the plate spring. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a sealing device 1 for a rotary engine capable of preventing a twist and a cut from occurring on a seal ring 5 without impairing the assemblage of the seal ring 5 and follow-up capability of a metal ring oil seal 2 in the sealing device 1 installed in the rotor 11 of the rotary engine and sealing a clearance between the rotor 11 and a side housing 13. SOLUTION: This sealing device comprises the metal ring oil seal 2 installed in an installation groove 12 provided in the rotor 11 and fitted closely to the side housing 13, a spring means 3 pressing the metal ring oil seal 2 against the side housing 13, and the seal ring 5 of a rubber-like elastic material installed in the groove provided in the side face of the metal ring oil seal 2 and fitted closely to the rotor 11. The cross sectional shape of the seal ring 5 is formed such that the side of the groove 4 seated on a groove bottom part is formed in a rectangular shape in cross section along a groove shape and formed so as to provide a flat seating surface 5c. The side thereof in close-contact with the rotor 11 is formed in an arc shape in cross section mainly by an O-ring. COPYRIGHT: (C)2004,JPO
246	LOW FLOW FLUID FILM SEALING FOR HYDROGEN-COOLED GENERATOR	JP2001061028	2001-03-06	JP2002010563A	2002-01-11	MAYER ROBERT RUSSELL; BAGEPALLI BHARAT SAMPATHKUMAR; AKSIT MAHMUT FARUK
PROBLEM TO BE SOLVED: To provide a low flow fluid film seal which can segregate substantially a hydrogen atmosphere and fluid in a cavity of a bearing from one another in a hydrogen-cooled generator. SOLUTION: In a hydrogen-cooled generator, a seal casing 30 has a chamber opening radially inwardly for receiving a pair of seal rings (40 and 42) forming a fluid film along the interface between the rings and the rotor. A spring (44) biases the seal rings against axial spaced flanges (36 and 38) of the seal casing and static oil sealing grooves are provided at the interface of the seal rings and flanges. A brush seal (46) is carried by one or both the seal rings or by the seal casing and has bristles for engaging the surface of the rotor. The combination of seal rings and brush seal forms a low flow fluid film seal maintaining the hydrogen atmosphere and oil on opposite sides of the housing wall and the seal casing segregated from one another.
247	STUFFING BOX RING	JP2000085888	2000-03-27	JP2000291807A	2000-10-20	FONTANA GIAN PAOLO
PROBLEM TO BE SOLVED: To provide a stuffing box ring used for a large size two stroke crosshead diesel engine equipped with a crosshead which can improve scavenging and sealing action efficiencies. SOLUTION: Stuffing box rings 10, 11, 12 are provided to be used for a stuffing box 1 of a large size two stroke diesel engine equipped with a cylinder reciprocatably accommodating a piston connected to a crosshead through a piston rod 3. The stuffing box 1 acts as an action way of the piston rod 3 extending from an air receiver chamber 4 to a crankshaft area 5. A hard wear resistant coating is applied on action surfaces of the stuffing box rings 10, 11, 12 which slide along the piston rod 3 in an active condition.

PURPOSE: To overcome problematic limitations in temperature and in form on packing boxes while ensuring their excellent sealing performance. CONSTITUTION: The seal lining of a packing box 2 is composed of joints 17 having a circular or approximately circular cross section and having different diameters so that they alternately rest on a rod 9 and on the housing of the packing box 2 in which they are pressed. Excellent liquid tightness is obtained and the joints 17 are metallic which makes it possible to use the packing box 2 at high temperature.

252	SHAFT SEALING DEVICE	JP10149693	1993-04-27	JPH06185627A	1994-07-08	INAGAKI TAIZO; TEZUKA KOICHI; SAGAWA TOMOYOSHI
PURPOSE:To prevent the crack and missing of a seal ring piece resulted from a step difference in a boundary between adjacent seal ring pieces and thermal expansion of the seal ring. CONSTITUTION:Seal rings on a stationary and a rotary side 19, 16 are respectively composed of a plurality of circular arc-shaped seal ring pieces 119, 116. A gas delta1 is formed between the adjacent seal ring piece on the stationary side 119, and a gap delta2 is formed between the adjacent seal ring pieces on the rotary side 116. The peripheral end face 119a of the seal ring piece 119 on the stationary side coincides with a radial direction line L. The peripheral end face 116a of the seal ring piece on the rotary side 116 partially coincides with the radial direction line L, but the remainder obliques from the line L.
253	SINTERED SLIDING MEMBER	JP17736893	1993-06-24	JPH0673391A	1994-03-15	SASAKI TAKAO; FUJITA KYOTARO
PURPOSE:To provide a sintered sliding member which is excellent in lubricity and abrasion resistance and can be used in a temp. range from normal temp. to about 800 deg.C. CONSTITUTION:This sintered sliding member comprises a stainless steel excellent in resistances to heat, chemicals, and corrosion as the bas material, 3-15wt.% cobalt, and 3-10wt.% lead oxide. When the member further contains 2-10wt.% graphite, its sliding characteristics, esp. its coefficient of friction, at about 100-450 deg.C are improved.

258	CYLINDRICAL FACE SEAL	JP11162388	1988-05-10	JPH01283476A	1989-11-15	JINNAI TAKESHI
PURPOSE:To minimize an initial leak amount due to the poor contact of a seal dam part on the internal surface of a seal ring by forming preliminarily a bearing pad part in such a way as to have a cylindrical face slightly larger than the seal dam part in diameter. CONSTITUTION:A baring pad part 22 on the internal surface of a seal ring 4 constituting a seal element 3 is so finished as to form a cylindrical face having a diameter slightly larger than a seal dam part 15. Consequently, even when the inner diameter faces of a seal ring 4 including the seal dam part 15 and the bearing pad part 22 is machined to have a taper in such a way to have a slightly larger diameter toward a low pressure side P2 due to a machining error, the seal dam part 15 of small diameter first comes in contact with a runner 14 due to the existence of a stepped part D.
