The fitting also includes a port that communicates with the central bore, and a cross bore near the second end. The fitting extends through the hole of the cup and a retaining pin is disposed in the cross bore to retain the cup between the first end and the second end of the fitting. Full Article
el Piston ring with improved lubrication delivery By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT A piston ring has a body member for sitting in a ring groove of a piston. The body member has an inner periphery, upper wall, lower wall and an outer periphery. The outer periphery has a concavity therein for storing lubricant therein. The upper wall has an outer section proximate to the outer periphery is constructed to be resiliently flexible between a flexed and unflexed position such during a portion of a power stroke, the volume of the concavity to store the lubricant is decreased by the flexing of the upper wall to the flexed position for expelling lubricant therefrom to a wall of the cylinder. The wall resiliently returns to the unflexed position during other times to allow excess lubricant from the wall of the cylinder to pass into the concavity. Full Article

el Device for the pulsed release of an amount of fluid that is stored in a storage housing By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A device for the pulsed release of an amount (3) of fluid that is stored in a storage housing (2) includes a piston (5) biased by a first spring (4) and movable within the storage housing (2) to dispense the fluid by the spring bias, when triggered by an actuator (6) to release a lock holding the piston in place (7). The lock (7) has individual catches (8) keeping the piston (5) in its pretensioned position and, when actuated by the actuator (6), releases the piston (5). Full Article
el Bumper made using a resistive implant welding process By www.freepatentsonline.com Published On :: Tue, 24 Mar 2015 08:00:00 EDT A bumper (10) created using a resistive implant welding process. The bumper includes a mounting plate portion (12) and a composite bumper portion (14). The mounting plate portion (12) is connected to the composite bumper portion (14) using a resistive implant welding process. In one embodiment, the present invention includes a bumper for a vehicle having a mounting plate (12) and a bumper portion (14). The bumper portion (14) includes at least one flange (24) formed as part of the bumper portion (14), a first contact area (28) formed as part of the mounting plate (12), and a second contact area (30) formed as part of the flange (24). A connection point is used to bond the first contact area (28) and the second contact area (30) such that the mounting plate (12) is connected to the bumper portion (14). Full Article
