Publication number: 20230173854Abstract: A valve assembly for a tire inflation/deflation system includes a body having a control port and a tire port, and a valve member for fluidly connecting or disconnecting the control port with the tire port. In one embodiment, the valve includes a fluid-operated damper having a damper chamber for controlling a timing of the valve member. A vent valve is provided for permitting excess fluid pressure to escape from the damper chamber. In another embodiment, the valve member includes a diaphragm separating first and second fluid chambers. A vent passage and at least one resilient fluid pressure-operated valve element are provided for enabling fluid to vent from the first chamber to the second chamber. Multiple-redundant valve elements may be provided to form an isolation gap that restricts contamination of the valve assembly.Type: ApplicationFiled: June 11, 2021Publication date: June 8, 2023Inventors: Shahed M. AHMED, Patrick D. O'CONNELL, Brian A. REYNOLDS, William B. MCCURDY, JR., Yufeng QI

Patent number: 7303053Abstract: A non-pressure head for a fluid cylinder, which includes a drain channel formed in the flange by a raised portion of the flange extending from a plane of the flange in the same direction as the head portion. The channel is cold formed in the flange. For the piston stop, the flange has an opening of a diameter smaller than a diameter of a piston on the piston rod to form a stop for the piston. A plurality of spaced ribs are provided between the flange and the head. The ribs are raised portions of the flange and the head and are cold formed in the flange and the head.Type: GrantFiled: September 21, 2004Date of Patent: December 4, 2007Assignee: New York Air Brake CorporationInventor: William B. McCurdy, Jr.

Patent number: 6565063Abstract: A choke for a brake control valve coming within the physical space limitation by forming a helical choke path. The choke includes a body having a passage and a plug in a passage. The helical path is created between and defined by the passage and the plug to form the choke. The length the passage is less an inch and the length of the plug is less than 0.25 inches. The body includes the first portion having an external thread and a stem portion. A filter is mounted on the stem portion. The first portion is mounted in a threaded opening in a first wall of the valve. The filter extends into an opening in a second wall of the valve and a cap mounted in the second opening contacts the filter and holds it secure on the stem.Type: GrantFiled: January 22, 2002Date of Patent: May 20, 2003Assignee: New York Air Brake CorporationInventors: Ronald O. Newton, William B. McCurdy, Jr.
