Abstract: A coolant filler neck assembly for a pressurized cooling system.

Abstract: A reciprocating pump includes a drive section and a pump section. The drive section has a reciprocating coil assembly to which alternating polarity control signals are applied during operation. A permanent magnet structure of the drive section creates a magnetic flux field which interacts with an electromagnetic field produced during application of the control signals to the coil. The coil assembly includes a drive member that drives a plunger assembly having a plunger and a valve stem movably interfitted within the plunger and having a lower poppet head. As the plunger is driven downwardly the plunger contacts the poppet head to drive it into the pump chamber to force the fluid therefrom. There is a gap between the poppet head and the plunger so that the initial downward movement of the plunger closes the gap to gain momentum before it contacts the poppet head and drives it downwardly.

Abstract: A method of manufacturing a fuel injector nozzle where a nozzle seat and a nozzle insert are made using a metal injection molding process. The nozzle seat and the nozzle insert are assembled and bonded together while in their green state. The resulting nozzle assembly is then debinded and sintered to obtain the desired fuel injector nozzle.
