Simplest way to increase pressure in a container?

Click For Summary
SUMMARY

The discussion focuses on methods to increase the internal air pressure of a container for an invention. Three primary methods are identified: introducing more air, increasing temperature, or decreasing volume. A proposed mechanism involves a lever system akin to a French press, incorporating a ratchet to maintain pressure. Suggestions from participants include using a bicycle tire pump, small CO2 cylinders, cardboard tube balloon pumps, or hypodermic syringes as potential solutions.

PREREQUISITES
  • Understanding of basic physics principles related to pressure and volume.
  • Familiarity with pneumatic systems and mechanisms.
  • Knowledge of materials suitable for airtight containers.
  • Experience with simple mechanical devices and levers.
NEXT STEPS
  • Research the design and functionality of bicycle tire pumps.
  • Explore the use of CO2 cylinders for pressurization applications.
  • Investigate the mechanics of lever systems and ratchet mechanisms.
  • Study the principles of pneumatic pressure control in closed systems.
USEFUL FOR

Inventors, engineers, and hobbyists interested in pressure systems, mechanical design, and pneumatic applications will benefit from this discussion.

I'm working on an invention which requires that I increase the internal air pressure of a container (while keeping it simple and cost-effective to produce).

I know my 3 options are to either: introduce more air into the container, increase the temperature, or decrease the volume.

One idea I had is trying to figure out a mechanism where the end user could simply press down on a lever, which would act similarly to a french-press (though the area being compressed would be air tight). There would be a ratchet to keep the lever from popping back up again due to pressure. Not sure if this would be the best approach.

Any ideas or suggestions on how to best tackle this problem?

Welcome to PF!

Your idea sounds good, but without highly detailed specifics of what you are trying to accomplish it is tough for us to answer with anything specific.
 
What shape is the container?
What is the initial absolute air pressure in the container?
What final absolute pressure do you require?
How quickly do you want the pressure to change?

A bicycle tyre pump?
Small C02 cylinder as used to inflate bike/car tyres?
Cardboard tube balloon pump?
Hypodermic syringe without needle?
 

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
