Abstract: A single-piece fastener includes a relatively hard clip and a relatively soft seal. The seal can be overmolded onto the clip. A thermal bond is formed between the seal and the clip to inhibit removal of the seal from the clip. The flexible nature of the umbrella of the clip and the seal can accommodate sealing openings in panels of varying thicknesses.

Abstract: A releasable fastener includes a tether and a clip adapted to be coupled to a first member. The tether has a first end releasably coupled to the clip, a second end adapted to be coupled to a second member that is moveable relative to the first member and a flexible member having first and second strands interconnecting the first and second ends of the tether. The second strand is frangible.

Abstract: A quick connect fastener system is provided. In another aspect of the present invention, a snap-in fastener is used for retaining an automotive vehicle interior trim member. A further aspect of the present invention employs a base and a resilient retainer, one of which includes a metallic portion and the other of which includes a polymeric portion. Moreover, a generally rigid polymeric base employs a channel operably receiving a metallic retainer in a laterally sliding manner to ease in assembly of the retainer to the base in an adhesive and screw-free manner.

Abstract: A two component line clip for fixing a line therein includes a body defining an aperture. The body is formed from a material having a first hardness. The aperture is defined in part by a rib. An insert is secured within the aperture. The insert is formed from a material having a second hardness less than the first hardness. The insert includes a feature that cooperates with the rib to secure the insert within the aperture. The insert is adapted to fix the line therein.

Abstract: A fastener first member connects to a second member by a flexible tether. A third member having multiple deflectable wings slides onto the second member. A first member male pin extends through a third member aperture to engage second member biasing elements, joining the first, second and third members. The first member also includes a hooked end.

Abstract: The downhole pump has a barrel with a reciprocating plunger therein. The barrel has a first one-way valve, while the plunger has a second one-way valve. A barrel chamber is formed between the two one-way valves. The barrel chamber expands when the reciprocal movement between the plunger and the barrel is an upstroke movement and then contracts when the reciprocal movement is a downstroke movement. A bypass channel is provided between the barrel and the plunger so as to provide communication around the plunger and its one-way valve. The bypass channel is open when the reciprocal movement is near an end of the upstroke movement. When open, pressure across the plunger can equalize and gas inside the barrel chamber can vent around the plunger and/or pressure can equalize across the plunger one-way valve so as to prevent gas lock and minimize stress on the sucker rods.
