Publication number: 20240093663Abstract: A DC power plant generating DC power from a variety of engines including a Stirling cycle engine. The DC power plant includes a relatively small start-up power source that is discontinued after the engine is running. A method for producing DC power for a load including starting up an engine using power supplied by a relatively small power supply supplemented by a capacitor bank, providing output from the engine to a generator, producing alternating current (AC) power by the generator, converting the AC power to direct current (DC) power, disabling output of the DC power during a first set of pre-selected conditions, limiting a rate of change of current of the DC power during a second set of pre-selected conditions, reducing conducted and radiated emissions of the DC power, disconnecting the DC power from the load under a third set of pre-selected conditions, and providing the DC power to the load.Type: ApplicationFiled: November 20, 2023Publication date: March 21, 2024Inventors: Andrew A. Schnellinger, James R. Lowell, Bryan A. Finseth, Christopher L. Barber, Jason M. Sachs, Donald J. Lucas, Shannon Prescott, Jeffrey W. Kite, Andras K. Fekete, Douglas R. Adams

Patent number: 10391996Abstract: An air dryer assembly with manifold system provides increased drying capacity for pressurized air systems, such as vehicle braking systems. A manifold connected to the supply ports of two adjacent air dryers allows parallel flow of air through the separate air dryers. An identical manifold connects to the delivery ports of the two air dryers to combine the clean, dry air from the delivery ports. Similar manifolds connect the control and purge ports of the dryers to allow simultaneous regeneration of the desiccant canisters. An assembly combining two air dryers, two pretreatment units, and manifolds connecting the supply, delivery, control, and purge ports of two air dryers is also disclosed.Type: GrantFiled: May 25, 2016Date of Patent: August 27, 2019Assignee: HALDEX BRAKE PRODUCTS CORPORATIONInventors: Andrew W. Adams, Michael R. Jenkins

Patent number: 8852327Abstract: An air dryer cartridge having an outer shell, an inner shell positioned within the outer shell, and a check valve positioned at least partially between the inner and outer shells. The inner and outer shells each have an inlet and an outlet. The outer shell is preferably operable to removably engage an air dryer. The check valve is operable to regulate the rate of flow of fluid through the outlet of the inner shell. Preferably, the check valve also seals between portions of the inner and outer shells and/or is operable to sealingly engage an air dryer.Type: GrantFiled: March 14, 2013Date of Patent: October 7, 2014Assignee: Haldex Brake Products CorporationInventors: Andrew W. Adams, David A. Prater, Michael R. Jenkins

Patent number: 7299740Abstract: A reciprocating axial displacement mechanism is disclosed generally comprising a housing, a rotating device, a displacement device having first and second undulating surfaces disposed in the housing, and a cam connected to the rotating device and disposed between the first and second undulating surfaces. The cam either has an undulating shape or has first and second undulating surfaces such that, as the cam rotates with the rotating device, the cam slides along the first and second undulating surfaces of the displacement device to cause the displacement device to move back and forth along the longitudinal axis of the rotating device. In certain embodiments, the displacement device is a pumping device, or an actuator for a pumping device, in a compressor.Type: GrantFiled: September 13, 2004Date of Patent: November 27, 2007Assignee: Haldex Brake CorporationInventor: Andrew W.

Patent number: 7249556Abstract: A compressor is disclosed generally comprising a cylinder head mounted to a cylinder block having a cooling chamber and a piston channel via a bolt. A piston is disposed in the piston channel and has a contact portion that contacts the channel wall, which is integrally formed with the cylinder block, as it slides within the channel. The bolt and the cooling chamber each extend from at least as high as the highest contact point between the contact portion of the piston and the channel wall to at least as low as the lowest contact point between the contact portion of the piston and the channel wall. In certain embodiments, the cooling chamber is located between the bolt and the piston channel. In some embodiments, a crankcase is integrally formed with the cylinder block.Type: GrantFiled: November 29, 2004Date of Patent: July 31, 2007Assignee: Haldex Brake CorporationInventors: Robert L. Koelzer, Michael R. Jenkins, Mark D. Schaake, Andrew W. Adams

Publication number: 20020127116Abstract: An axial piston compressor produces air supplied to an air system of a vehicle, typically a heavy duty truck through a plurality of pistons held within a stationary block, and the movement of the pistons is predicated through the control of a pivotal swash plate. The pistons are idle in a neutral position of the swash plate, wherein a pressure above the pistons in the cylinder block counterbalances a thrust generated by an actuator upon the plate positioned in a plane extending perpendicular to a drive shaft. The plate oscillates in response to a pressure drop above the pistons causing the actuator to expand toward the plate and exert a thrust exceeding the lowered pressure above the pistons and enabling the swash plate to provide the pistons with reciprocal motion.Type: ApplicationFiled: March 12, 2001Publication date: September 12, 2002Inventors: Robert L. Koelzer, Andrew W. Adams, Mark D. Schaake, Michael R. Jenkins
