AIR ENGINE WITH ROTATABLE INTAKE-EXHAUST MECHANISM

摘要

An air engine includes a cylinder, a piston, a gas supply and an intake-exhaust mechanism. The gas supply supplies a compressed gas to move the piston reciprocating in the cylinder. The intake-exhaust mechanism connected to the cylinder and the gas supply includes a body and an intake-exhaust assembly. The body has a chamber, and an intake channel, an exhaust channel, an inlet port and an outlet port, which communicate with the chamber. The intake-exhaust assembly, rotatable within the chamber, controls the inlet port to be connected to the intake channel, and further controls the outlet port to be connected to the exhaust channel, so that the compressed gas enters the cylinder via the inlet port and the intake channel to drive the piston. After driving the piston, the compressed gas becomes an exhaust gas, which is exhausted from the cylinder via the exhaust channel and the outlet port.

1. An air engine, comprising:
a cylinder; a piston capable of reciprocating in the cylinder; a gas supply supplying a compressed gas to move the piston; and an intake-exhaust mechanism, which is connected to the cylinder and the gas supply and comprises:
a body having a chamber, and an intake channel, an exhaust channel, an inlet port and an outlet port, which communicate with the chamber, wherein the intake channel and the exhaust channel communicate with the chamber and the cylinder; andan intake-exhaust assembly, which is rotatable within the chamber, controls the inlet port to be connected to the intake channel or not upon rotation, and controls the outlet port to be connected to the exhaust channel or not upon rotation, so that the compressed gas enters the cylinder via the inlet port and the intake channel to drive the piston, wherein after driving the piston, the compressed gas becomes an exhaust gas, which is exhausted from the cylinder via the exhaust channel and the outlet port.
