  • Liquid pump with cavitation mitigation
    Patent number: 10557446
    Abstract: A liquid pump applicable in a fuel system such as a common rail fuel system includes a valve assembly having a valve stack with axially aligned components, dead volume, and vapor-distributing flow channels, for cavitation mitigation. An inlet valve meters a flow of liquid into the pump for pressurization by a plurality of reciprocating plungers operated by way of a rotating camshaft.
    Type: Grant
    Filed: July 5, 2017
    Date of Patent: February 11, 2020
    Assignee: Caterpillar Inc.

  • Fluid injector actuator with resilient armature overtravel feature
    Patent number: 9359985
    Abstract: An actuator for a valve assembly includes a body having an internal surface defining a bore therein, the internal surface including a first body shoulder at least partly facing a longitudinal direction defined along a longitudinal axis of the bore; a first armature disposed within the bore, the first armature being configured to generate a force in response to a first electromagnetic field acting thereon; a first stem operatively coupled to the first armature and a first valve of the valve assembly; a first pair of shoulders disposed on the first stem, the first pair of shoulders at least partly facing one another and defining a first stem circumferential groove therebetween; and a first valve travel spacer disposed about the first stem circumferential groove, and disposed in interference with the first body shoulder along the longitudinal direction.
