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.

Patent number: 9259681Abstract: An air dryer with a rotor and desiccant positioned within an interior chamber of the rotor. The desiccant is positioned within the interior chamber of the rotor between the inlet and the outlet. The desiccant is configured to adsorb at least some of the water contained within air flowing from an inlet to an outlet of the rotor. As the rotor is rotated at a regeneration speed at least some of the water adsorbed by the desiccant moves to the outer surface of the desiccant and at least some of the water is separated from the outer surface of the desiccant. The rotor directs water separated from the outer surface of the desiccant to at least one opening in the rotor. A method for drying air by sending the air through desiccant and rotating the desiccant at a regeneration speed to separate water from the desiccant.Type: GrantFiled: October 31, 2013Date of Patent: February 16, 2016Assignee: HALDEX BRAKE PRODUCTS CORPORATIONInventor: Michael R.

Patent number: 7318709Abstract: A valve assembly is disclosed generally comprising first and second valve plates mounted between the housing for a pump mechanism and a cover, the first plate having flexing flaps corresponding to apertures in the second plate, and the second plate having flexing flaps corresponding to apertures in the first plate. The flexing flaps and apertures create inlet and outlet valves for fluid being received into and discharged from the pump mechanism. In some embodiments, the valves facilitate the flow of air received and discharged through inlet and outlet ports in a compressor head. In some embodiments, the valves facilitate the flow of air received from an inlet port in a compressor housing.Type: GrantFiled: August 27, 2003Date of Patent: January 15, 2008Assignee: Haldex Brake CorporationInventors: Robert L.

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.
