Abstract
An oxygen-compression apparatus has a driving device, an output shaft, two crank devices, two cylinders and multiple hoses. The crank devices are attached respectively to two ends of the output shaft, and each crank device has a rotating arm and a pushing arm pivotally attached to the rotating arm. The cylinders are connected respectively to the crank devices. Each cylinder has a housing and a piston rod. The piston rod has a first end extending into the housing to form a compression chamber in the housing and a second end pivotally connected to one of the pushing arms. The hoses are connected between the compression chambers of the cylinders. Accordingly, the oxygen-compression apparatus can conveniently pump oxygen into a gas tank at a desired pressure and can simultaneously apply oxygen to a user with an auxiliary output hose.
