Abstract
In variants, a two-stage pump can include a piston and a cylinder cooperatively defining a first stage in front of the piston fluidly connected to a second stage behind the piston, wherein a forward stroke of the piston pressurizes working fluid in the first stage and forces pressurized working fluid into the second stage, and a backward stroke of the piston further pressurizes working fluid in the second stage and exhausts pressurized working fluid out a pump exhaust.
Claims17
A pump, comprising:
- a cylinder comprising a cylinder first end and a cylinder second end;
- a piston housed within the cylinder and comprising a piston front face, piston back face, and a piston rod extending through the cylinder second end, wherein the cylinder and piston cooperatively define:
- a first stage between the cylinder first end and the piston front face;
- and
- a second stage between the cylinder second end and the piston back face;
- wherein the piston is operable between:
- a forward stroke, during which the piston pressurizes working fluid within the first stage to a first pressure and forces the working fluid from the first stage into the second stage;
- and
- a backward stroke, during which the piston pressurizes working fluid from the first pressure to a second pressure within the second stage and forces the working fluid from the second stage out of the pump;
- a set of cylinder cooling channels thermally connected to and extending alongside the cylinder;
- and
- a set of cooling heads mounted to the piston and complementarily nested within the cylinder cooling channels;
- wherein actuation of the piston relative to the cylinder actuates the cooling heads within the cylinder cooling channels to convect heat from the cylinder.

A tire inflation system comprising:
- a cylinder;
- a piston comprising a piston head housed within the cylinder, wherein the piston head divides the cylinder into a first stage and a second stage, wherein the first stage is fluidly connected to an ambient environment and the second stage, and the second stage is fluidly connected to a fluid reservoir;
- wherein the piston is configured to operate between:
- a forward stroke that pressurizes fluid in the first stage to a first pressure and forces the fluid from the first stage into the second stage:
- and
- a backward stroke that pressurizes fluid in the second stage from the first pressure to a second pressure and forces the fluid from the second stage into the fluid reservoir;
- and
- an integrated cooling system powered by piston actuation, wherein the integrated cooling system comprises:
- a set of cylinder cooling channels thermally connected to and extending alongside the cylinder;
- and
- a set of cooling heads mounted to the piston and complementarity nested within the cylinder cooling channels;
- wherein actuation of the piston relative to the cylinder actuates the cooling heads to force a cooling fluid through the cylinder cooling channels.
