20080290609 | Carrier Frame Seal with Mount Points to Seal Motor Components - The invention relates to a frame member seal comprising at least two fixing devices, which are configured from plastic or elastomer and are designed to project in corresponding orifices in front of at least one component that is to be sealed. | 11-27-2008 |
20090008883 | High-Pressure Fuel Pump and Seal System For High-Pressure Fuel Pump - A high-pressure fuel pump with seal system that is usable under the conditions of “high speed”, “high pressure” and “fuel resistance”. There is provided a high-pressure fuel pump comprising an axle capable of reciprocating motion in the pump and seal system ( | 01-08-2009 |
20090243229 | Packing material fitting structure - A packing material fitting structure that prevents the packing material from easily dropping out and facilitates mounting and fixing of the packing material in a packing material fitting place in a part such as a casing or a cover of an engine or a pump with sealing ability. The fitting structure is provided with a packing material having an annular main body portion and a plurality of projections each having a main protruding portion formed to protrude from the annular main body portion and an auxiliary protruding portion formed integrally in the vicinity of the main protruding portion, the projections being formed with an appropriate spacing in the longitudinal direction of the main annular main body portion. The fitting structure is also provided with a casing having formed therein an annular fitting groove for inserting the annular main body portion of the packing material. A cutout portion into which only the main protruding portion of the projection is inserted is formed in a groove wall portion of the fitting groove. An integral forming region of the auxiliary protruding portion and the annular main body portion has a width substantially equal to or larger than a width of the fitting groove. In the packing material, a projection formation location is pressed and fixed only by the cutout portion and both groove wall portions in the vicinity of the cutout portion. | 10-01-2009 |

20120146294 | BOOT SEAL FOR VARIABLE COMPRESSION-RATE ENGINE - A boot seal for variable compression-rate engine includes a cylindrical boot-seal element, and a deformation inhibitor. The boot-seal element has an end being fixed to the cylinder block of the variable compression-rate engine, and another end being fixed to the crankcase. Moreover, the boot-seal element is provided with a bellows-shaped cylindrical deformer being made of an elastically deformable material. The deformation inhibitor is disposed outside or inside the boot-seal element in order to control the boot-seal element so as to deform outwardly or inwardly to a predetermined deformation magnitude. | 06-14-2012 |
20120248712 | BOOT SEAL FOR VARIABLE COMPRESSION-RATE ENGINE - A boot seal for variable compression-rate engine includes a boot-seal element, and a reinforcement member. The boot-seal element includes an inner layer, and an outer layer. The inner layer is disposed on the inner face of the boot-seal element, and is composed of a fluorinated rubber. The outer layer is disposed on a more outer side of the boot-seal element than is the inner layer. Moreover, the boot-seal element is formed in a circumferentially developed state so as to have circumferential ends, and is then completed by joining the circumferential ends with each other. Thus, the boot-seal element makes an elastically deformable cylindrical bellows shape having a root that dents inward diametrically. In addition, the reinforcement member is disposed in the root of the cylindrical bellows-shaped boot-seal element at least. | 10-04-2012 |
