摘要： A system for producing mechanical energy. In some embodiments, the system includes a first source providing a first fluid, a fluid pressurization device, a second source supplying a second fluid, a first motor, and a second motor. The fluid pressurization device draws in the first fluid from the first source and increases the pressure of the first fluid. The first motor is driven by the second fluid, the second fluid decreasing in pressure and the first motor powering the fluid pressurization device as the second fluid passes through the first motor. The second motor receives a mixture of the first fluid from the first motor and the second fluid from the fluid pressurization device, whereby the second motor produces the mechanical energy.

摘要： An overspeed control means for pneumatic tools which includes a split ring valve slidably arranged in a circumferential groove formed in a cage member affixed to the rotor shaft of the tool. When the cage member exceeds a predetermined rotational speed, the ring valve will expand and be moved, by pressure differential acting thereupon, into engagement with a valve seat to block holes in a flow circuit for pneumatic medium being conducted to the rotor of the tool, whereby tool operation is terminated.

摘要： A novel turbine motor spindle assembly for a spindle-mounted pneumatic tool, especially in a live tool environment is described. The novel turbine motor spindle assembly includes a manifold with a front end and a rear end. The manifold includes an air intake passage for receiving pressurized air. The pressurized air is directed axially through a drive shaft rotatably coupled to the front end. The pressurized air drives a turbine motor assembly and a drive shaft. The drive shaft is mounted inside a housing is self-lubricating. The turbine motor assembly includes tangential openings for expelling exhaust air therefrom. The turbine motor housing is mechanically coupled to the front end of the manifold with an exhaust air passage for directing exhaust air from the one or more tangential openings out through the rear end of the manifold.
