Abstract: A device for metering fluids includes a block provided with a channel connecting a fluid inlet in fluid communication with a fluid outlet. The device also includes a filter assembly within the channel and a fluid meter within the channel at a position downstream from the filter assembly. The device further includes a check valve assembly within the channel at a position downstream from the fluid meter. In addition, the device includes a calibration valve assembly within a channel section of the channel between the fluid outlet and the fluid meter. The calibration valve assembly is operable to move between a first position allowing passage of fluid from the fluid meter towards the fluid outlet and a second position blocking the passage of fluid from the fluid meter towards the fluid outlet.

Abstract: The invention relates to a device for metering fluids comprising a solid block provided within said block with a fluid inlet being in fluid communication with a fluid outlet via a channel; a filter assembly being accommodated within said channel; a fluid meter being accommodated within said channel at a position downstream from the filter assembly; a check valve assembly being accommodated within said channel at a position downstream from the fluid meter. It is an object of the invention to provide a metering device as described above with an additional functionality, which will improve the accuracy of the metering device during use.

Abstract: The coupler tool of the present invention includes a ring having oppositely facing radial flat parallel sides and radial outer edges beveled toward one another. Extending axially outwardly from one of the sides is a handle portion. The handle portion includes a pair of laterally spaced apart arms extending axially outwardly from diametrically opposite areas of one side of the ring and a hand grip extending between the arms in axially spaced relation from such one side.

Abstract: A system for periodically maintaining non-fuel fluids required for proper performance by various apparatus and for reporting non-fuel fluid maintenance action taken. Maintenance systems include means for replacing, replenishing or renewing non-fuel fluids or renewing non-fuel fluid filters. Reporting systems include means for communicating information between on- and off-apparatus sub-systems and for generating reports that document non-fuel fluid maintenance actions taken.

Abstract: Piston rod assembly includes a composite piston rod having an entrapment ridge along the length thereof, and a non-integral metallic piston head having two separate piston head sections which are welded together in preloaded engagement against opposite sides of the entrapment ridge. The entrapment ridge has oppositely facing external tapered ramp surfaces which are engaged by correspondingly tapered internal ramp surfaces on the respective piston head sections. When the piston head sections are initially brought into engagement with opposite sides of the entrapment ridge, there is a slight gap between the inner faces on the piston head sections which determines the amount of preload force that must be applied to the piston head sections to eliminate the gap and bring the inner faces into substantial mating engagement with each other for welding.
