    Abstract: A pumping mechanism includes a barrel assembly having a plunger bore. The plunger bore has a longitudinal axis. The pumping mechanism also includes a plunger configured to slide within the plunger bore parallel to the longitudinal axis. The pumping mechanism further includes a push rod separate from the plunger. The push rod is configured to move away from the plunger to be spaced from the plunger, and the push rod is further configured to move within the plunger bore to push the plunger.

    Abstract: A port injection system for gaseous fuels may include an injector body defining a hydraulic fluid inlet chamber, a hydraulic fluid exit passageway, a hydraulic fluid actuation passageway, a check valve inlet passageway fluidly connected with the hydraulic fluid actuation passageway, a valve chamber, and a gaseous fuel inlet chamber. An electrical solenoid actuator may be mounted to the injector body, with the electrical solenoid actuator including a movable armature, and a poppet valve connected to the movable armature and disposed within the valve chamber. The poppet valve may be movable between a pressurized hydraulic fluid flow blocking position and a pressurized hydraulic fluid flow passing position. A check valve may be disposed within the check valve inlet passageway. A gas admission valve may be disposed at least partially within the gaseous fuel inlet chamber and in contact with the check valve such that movement of the check valve by hydraulic fluid entering the check valve inlet passageway results in actuation of the gas admission valve away from a normally closed position closing off the gaseous fuel inlet chamber to a fuel injection position wherein gaseous fuel is allowed to flow from the gaseous fuel inlet chamber into an intake manifold or intake port of an engine on which the injector body is mounted.

    Abstract translation: 用于气体燃料的端口注入系统可以包括限定液压流体入口室的喷射器主体，液压流体出口通道，液压流体致动通道，与液压流体致动通道流体连接的止回阀入口通道，阀室和 气体燃料入口室。 电螺线管致动器可以安装到喷射器主体，电磁螺线管致动器包括可移动衔铁，以及连接到可移动衔铁并且设置在阀室内的提升阀。 提升阀可以在加压液压流体阻止位置和加压液压流体流动位置之间移动。 止回阀可设置在止回阀入口通道内。 气体入口阀可以至少部分地设置在气体燃料入口室内并与止回阀接触，使得通过进入止回阀入口通道的液压流体的止回阀的运动导致气体进入阀的致动远离 通常关闭位置将气态燃料入口室关闭到燃料喷射位置，其中允许气体燃料从气态燃料入口室流入其中安装有喷射器主体的发动机的进气歧管或进气口。

    Abstract: A support system for a pump having a plurality of pumping elements is disclosed. The support system may include a first flange, a second flange opposite the first flange, and a support member between and abutting the first and second flanges. The support system may further include a plurality of fasteners, each being coaxially aligned with a respective one of the plurality of pumping elements, wherein each of the plurality of fasteners is configured to draw the actuating and pressurizing ends against the support member.
