Patent number: 6478857Abstract: A total delivery oxygen concentration system is provided to supply concentrated oxygen to end users having a variety of oxygen capacity requirements. The system includes a first oxygen concentrating device that may be operated either singularly to produce a first flow of concentrated oxygen or in conjunction with a supplemental oxygen concentrating device. When operating in conjunction with the supplemental oxygen concentrating device, the first oxygen concentrating device serves as a source of compressed air for the supplemental oxygen concentrating device and receives a second flow of concentrated oxygen from the supplemental oxygen concentrating device to provide a combined concentrated oxygen flow to the end user.Type: GrantFiled: January 7, 2002Date of Patent: November 12, 2002Assignee: Respironics, Inc.Inventor: Michael P. Czabala

Patent number: 6382931Abstract: A muffler assembly for muffling noises associated with a compressor. The muffler assembly is mounted on the compressor such that the two move as a solid body. The muffler assembly includes an intake having a hollow interior adapted to receive a first flow of gas from the ambient environment. A baffle disposed in the hollow interior of the intake restricts the flow of gas through the intake. In one embodiment, the baffle defines at least a portion of a plurality of fluid portals that separate the first flow of gas into a plurality of flows of gas as the gas passes from a first side of the baffle to a second side of the baffle. As a result, the first flow of gas is disturbed and noise from the compressor is thereby attenuated. In another embodiment, a plurality of baffles are disposed in the hollow interior of the intake to define a tortuous path for the flow of gas through the intake for attenuating noise.Type: GrantFiled: August 10, 2001Date of Patent: May 7, 2002Assignee: Respironics, Inc.Inventors: Michael P. Czabala, Robert W. Murdoch

Patent number: 6190441Abstract: A multi-chamber canister for a pressure swing absorption system within a general housing assembly. The chambers include a first molecular sieve chamber for receiving a first molecular sieve for separating air from the ambient environment into a concentrated gas and at least a second molecular sieve chamber disposed within the housing assembly for receiving a second molecular sieve for separating air from the ambient environment into a concentrated gas component. Furthermore, a supply chamber is disposed within the housing for receiving air from the ambient environment and for communicating air to either first or second molecular sieve chambers.Type: GrantFiled: December 6, 1999Date of Patent: February 20, 2001Assignee: Respironics Georgia, Inc.Inventors: Michael P. Czabala, Robert W. Murdoch

Patent number: 5996731Abstract: A muffler assembly for muffling noises associated with a compressor. The muffler assembly includes an air intake having a hollow interior for receiving air from the ambient environment when the compressor is operating. A baffle is located within the interior of the intake for restricted passage of the air through the intake. A fluid portal is defined within the baffle for enabling fluid to pass from one side of the baffle to the other side of the baffle and subsequently through said air intake. An attenuator is disposed within the fluid portal for attenuating noise and the attenuator disturbs the soundwaves associated with the operation of the compressor.Type: GrantFiled: February 24, 1998Date of Patent: December 7, 1999Inventors: Michael P. Czabala, Robert W. Murdoch

Patent number: 5916349Abstract: A piston assembly comprising a piston sleeve having an interior wall, a piston carried in the piston sleeve, a cup seal carried by the piston which engages the interior wall of the piston sleeve, and a valve plate matingly adapted to receive the piston sleeve. A firm thermal-insulating barrier is disposed between the valve plate and the piston sleeve for reducing the heat flow from the valve plate to the piston sleeve.Type: GrantFiled: November 20, 1997Date of Patent: June 29, 1999Inventor: Michael P. Czabala
