Abstract
An air switch including a housing, a lubrication port, a first air inlet port and an exhaust port is disclosed. The housing includes a chamber. The lubrication port is disposed to deliver lubrication into the chamber. The first air inlet port is disposed to introduce air into the chamber. The exhaust port is disposed to exhaust the lubrication and air from the chamber.
Claims34
An air switch comprising:
- a housing having a chamber;
- a lubrication port disposed on the housing to deliver lubrication into the chamber;
- a first air inlet port disposed on the housing to introduce air into the chamber;
- a second air inlet port disposed on the housing to introduce air into the chamber;
- an exhaust port disposed on the housing to exhaust lubrication and air from the chamber;
- and
- a cam rotatably mounted in the chamber, wherein the cam is rotatable to a first position wherein the first and second air inlet ports are closed when the cam is in the first position and the lubrication port is in fluid communication with the exhaust port such that lubrication can flow from the lubrication port to the exhaust port when the cam is in the first position.

The air switch of claimed wherein the chamber is unpressurized during normal operation of the air switch.
An air switch lubrication system comprising;
- a chamber;
- a lubrication port disposed to deliver a lubricant into the chamber;
- a first air inlet port disposed to introduce pressurized air into the chamber;
- an exhaust port for exhausting the lubricant and air from the chamber;
- wherein the air switch lubrication system is configured such that the introduction of pressurized air into the chamber from the first air inlet port circulates the lubricant introduced into the chamber from the lubrication port throughout the chamber.
