Abstract: A unitized seal includes a unitizing joint which is remotely spaced from a seal lip. The seal requires only two stampings with one elastomeric element bonded to one of the stampings. The remaining stamping forms a one piece wear sleeve having a first section with a wear surface which is engaged by a seal lip formed on the elastomeric element to provide a seal. A second section of this stamping extends angularly away from the wear surface and includes a terminal end which cooperates with the elastomeric element bearing stamping to form the unitizing joint.

Abstract: A fuel injector train having a variable injection rate includes a fuel injector having a plunger and a plunger biasing device having a predetermined spring rate for controlling the injection rate of the injector. A cam assembly is mounted to impart force through a push rod to a rocker arm which communicates the force of the cam assembly to the fuel injector plunger. In some embodiments, the push rod collapses axially a short distance in response to axial force applied thereto. The push rod has an inherent bias against collapsing that is less than the total bias of the injector biasing device so that during a portion of the injection cycle, part of the force imparted to the push rod collapses the push rod to operate the injector at a reduced rate. In another embodiment, the rocker arm is formed with a closable gap between its first and second ends, and the gap has an inherent bias against closing that is less than the total bias of the fuel injector biasing device.

Abstract: A side channel blower of the type used as a combustion air blower for motor vehicle heaters wherein a vaned impeller compresses air within a channel formed in a blower. The blower housing has an inlet opening and a discharge opening, between which there is a cross piece. In order to increase the compression pressure which can be achieved with the side channel blower, the inlet opening is in an axial plane and empties into the side channel in the direction of rotation of the impeller. Furthermore, the cross piece has a substantially uniform length in the circumferential direction of the flower and extends into close proximity to a boundary edge of the inlet opening that extends across the flow channel so that an axial projection of the inlet opening onto the plane of rotation of the impeller is as small as possible relative to the area of the inlet opening in the axial plane.

Abstract: A composite panel, with a core member; a cover plate glued to the upper side of the core member, and also a cover plate glued to the lower side; and with an edge strip secured to the rim of the core member. The composite panel substantially avoids dimensional tolerance problems which can arise at the edge strip, and high demands made during technical use, and by designers, can be met by the panel. The edge strip includes two corner strips which extend centrally from the edge strip and which have a width which is precisely, i.e. with negligible tolerance, predetermined. The edge strip also has a central strip. The core member comprises peripheral ledges which extend centrally from the upper and lower sides with precisely predetermined thickness, and an intermediate component arranged between the ledges. The thickness of the peripheral ledges is adapted to the width of the corner strips of the edge strip.

Abstract: A webbing retractor for use in a seatbelt system for a vehicle designed to protect an occupant when an emergency situation of the vehicle occurs. When the occupant has a webbing fastened after it has been substantially fully rewound, if an acceleration sensor senses a predetermined level of acceleration acting on the vehicle, the sensor engages with a lock wheel to lock a webbing take-up shaft from rotating in a direction in which the webbing is unwound. When the webbing is substantially fully unwound from the take-up shaft, an engagement lever opposes the lock wheel. In this state, the webbing is allowed to be rewound, but when it is unwound, the engagement lever, which receives the rotational force from the take-up shaft through friction, is engaged with the lock wheel, thus causing the rotation of the lock wheel to be delayed with respect to the rotation of the take-up shaft. Sensing this delayed rotation, a lock means locks the take-up shaft from rotating in the webbing unwinding direction.
