Abstract
A metering unit is provided. The metering unit includes a metering pin analog and a translation shaft. The metering pin analog is configured to translate about the translation shaft in a first direction in response to a load pressure acting on an annular region of a bottom portion of the metering pin analog. The metering pin analog is configured to translate about the translation shaft in a second direction opposite the first direction in response to the load pressure ceasing.
Claims15
A metering unit, comprising:
- a metering pin analog;
- and
- a translation shaft, wherein:
- the metering pin analog is configured to translate about the translation shaft in a first direction in response to a load pressure acting on an annular region of a bottom portion of the metering pin analog, and
- the metering pin analog is configured to translate about the translation shaft in a second direction opposite the first direction in response to the load pressure ceasing, wherein the metering pin analog includes a plurality of variable area flutes machined into an outer circumference of a side portion of the metering pin analog and wherein each of the plurality of variable area flutes has a first area at a first end of the side portion that transitions to a second area at a second end of the side portion.
