A flow limiter component including a monocoque body having first, second, and third sections along a longitudinal axis. The first section includes a first end defining a first edge of the monocoque body and a bordering second end, and a first inner diameter defining a first chamber inside the first section. The second section includes a solid wall, with an orifice disposed therein, in fluid communication with the first chamber, the orifice defined by a second inner diameter. The third section includes a third end bordering the second section and a fourth end defining a second edge of the body, and a third inner diameter, the third inner diameter defining a second chamber in the third section. The second chamber is in fluid communication with the orifice. The first inner diameter is greater than the third inner diameter, and the third inner diameter is greater than the second inner diameter.

Multi-function orifice subassembly for flow limiters

In an example, a pressure relief valve is described. The pressure relief valve comprises a housing configured to allow fluid flow therethrough. The pressure relief valve also comprises an adapter having interior threads, where the adapter is attached to the housing such that the adapter is positioned at least partially within the housing. The pressure relief valve also comprises an orifice plate having an orifice formed therein to allow fluid flow therethrough, where the orifice plate comprises exterior threads that engage with the interior threads of the adapter to couple the orifice plate to the adapter. The pressure relief valve also comprises a spring disposed within the housing. The orifice plate translates via engagement of the exterior threads with the interior threads to calibrate a spring force of the spring.

Example systems, apparatuses and methods are disclosed for gear reduction. An example system comprises a second gear configured to be disposed in mesh with a first gear coupled to an input shaft. The system further comprises a carrier housing configured to be fixably disposed within the second gear. The system further comprises a third gear configured to be disposed within the carrier housing; a fourth gear configured to be disposed in mesh with the third gear, wherein the third gear is further configured to rotate about the fourth gear; an anti-backlash gear coupled to the fourth gear and configured to be disposed in mesh with the third gear; and a fifth gear configured to be disposed in mesh with the third gear. The second gear, the fourth gear, the anti-backlash gear, and the fifth gear are configured to be disposed along a common axis of rotation.
