Inlet control valve with snap-off coil assembly

In a solenoid actuated inlet control valve for a fuel pump, the risk of fuel leakage from the control valve in the event of damage to the electromagnetic actuator for the inlet control valve is reduced by hydraulically isolating an actuation module containing the electromagnetic coil from a delivery module containing the hydraulic flow paths, and providing a breakaway connection between the actuation module and the delivery module.. . ...

Direct magnetically controlled inlet valve for fuel pump

An inlet valve assembly for a fuel pump comprises a valve assembly inflow path and valve assembly outflow path; a magnetic valve member situated in an intermediate flow path fluidly linking the inflow path and the outflow path; a magnetic pole adjacent the valve member; and a selectively energizable coil for generating a magnetic flux directly magnetically coupling the pole and the valve member; whereby the valve member opens and closes fluid communication between the inflow path and the outflow path in response to the energized state of the coil.. . ...

Woven mesh debris shield for fuel injector

A debris shield in the high pressure fuel supply passage of a fuel injector, upstream of a bypass branch line leading to a control valve, comprising a rigid tube with a central passage aligned with the fuel supply passage and narrow flow paths through which high pressure fuel is filtered for removal of debris before delivery to the branch line, wherein the tube has opposed ends that are sealingly compressed between spaced apart stop surfaces along the fuel supply passage. The flow paths can be can be bores, slots, or circuitous transverse flow paths formed by woven or ribbon wrapped mesh.. ... Stanadyne Corporation

Single piston pump with reduced piston side loads

In a tappet-driven single piston pump, piston side loads caused by return spring out-of-squareness are eliminated by effectively piloting the piston return spring, preferably the associated spring seat, by the tappet, thereby allowing the tappet to bear the spring side load. The piston engages and is returned by the spring seat, but radial clearance between the piston and spring seat is greater than radial clearance between the spring seat and tappet, thus eliminating side loading imparted to the piston. ...
