Patent number: 9133852Abstract: An engine system having a compressor coupled to an engine and supplying air to an intake manifold, a throttle controlling the supply of air from the compressor to the intake manifold, a compressor recirculation valve (CRV) having a pneumatic control chamber, and a throttle aspirator having its motive section in fluid communication with an inlet of the throttle and its discharge section in fluid communication with an outlet of the throttle and its suction port in fluid communication with the pneumatic control chamber of the CRV. Such an engine system automatically minimizes surge during boost without a control system activating the CRV. Here, the CRV operates purely on the changes in pressure within the system forming a loop that resets itself. In another embodiment, a gate valve and a vacuum canister may be included rather than having the throttle aspirator directly connected to the CRV's pneumatic control chamber.Type: GrantFiled: June 13, 2014Date of Patent: September 15, 2015Assignee: DAYCO IP HOLDINGS, LLCInventors: Dave Fletcher, Brian M.

Patent number: 9121495Abstract: Pulley assemblies are disclosed that include a pulley body, a hub disposed within the bore of the pulley body, and a one-way clutch concentric about the hub. The one-way clutch has a plurality of cantilevered members that each include a friction surface and a cantilevered end and a biasing member in contact with one cantilevered member to bias the cantilevered members into continuous frictional engagement with the bore of the pulley body. Each of the cantilevered members is pivotable about its cantilevered end and is partially nested within an adjacent cantilevered member to form an annular body. This construction places the friction surface of each cantilevered member facing the bore of the pulley body. In operation, the pulley body rotates in a predominant direction which activates the plurality of cantilevered members to link the pulley body to the hub for simultaneous rotation.Type: GrantFiled: March 15, 2013Date of Patent: September 1, 2015Assignee: DAYCO IP HOLDINGS, LLCInventors: Anthony E. Lannutti, Kevin G. Dutil, James H. Miller

Publication number: 20150159677Abstract: An aspirator for creating vacuum is disclosed that includes a housing defining a fluid passageway with a first tapering portion and a second tapering portion. Each tapering portion has a larger internal opening and a smaller internal opening, the smaller openings facing one another. The aspirator includes a gate positioned between and in fluid communication with the first and second tapering portions, the gate having a first Venturi tube with a Venturi opening creating vacuum when fluid flows in a direction and a second Venturi tube with a Venturi opening that creates vacuum when fluid flows in the opposite direction. The Venturi openings are in fluid communication with a suction port, and the first and second Venturi tubes may provide different mass flow rates through the aspirator. An engine system having an aspirator with a gate having a first bore and a second bore and an actuator is also disclosed.Type: ApplicationFiled: December 9, 2014Publication date: June 11, 2015Applicant: DAYCO IP HOLDINGS, LLCInventors: Keith Hampton, David Fletcher, Brian M.

Publication number: 20150159665Abstract: Recirculation systems for engine intake air are disclosed having a turbocharger compressor with an inlet and an outlet, a recirculation pathway connecting fluid flow from the outlet of the turbocharger compressor to fluid flow into the inlet of the turbocharger compressor, and a recirculation valve assembly controlling fluid flow through the recirculation pathway. The recirculation valve assembly includes an actuator operating a valve coupled to an aspirator assembly that produces vacuum when the fluid flows through the recirculation pathway from the inlet to the outlet and when fluid flows through the recirculation pathway from the outlet to the inlet. Fluid flows through the recirculation pathway from the outlet to the inlet when the turbocharger generates boost. The vacuum generated by the aspirator assembly is in fluid communication with the actuator to move the valve between two or more positions.Type: ApplicationFiled: December 10, 2014Publication date: June 11, 2015Applicant: DAYCO IP HOLDINGS, LLCInventors: David Fletcher, Brian M.

Publication number: 20150090355Abstract: A solenoid-powered gate valve that provides a reliable, high quality seal with a reduced operating force requirement. The valve includes a solenoid coil and armature connected to a valve mechanism, with the valve mechanism including a conduit having a connection opening, an oppositely-disposed pocket, and a sprung gate assembly linearly movable between the connection opening and the pocket. The sprung gate assembly includes a first gate member with an opening, a second gate member with an opening, and an endless elastic band retained between the first and second gate members, with the openings and endless elastic band collectively defining a passage through the sprung gate assembly, with the first and second gate members being mechanically coupled to the armature for reciprocating linear movement between the connection opening and the pocket. The endless elastic band allows an interference fit within the pocket with reduced frictional opposition to gate movement.Type: ApplicationFiled: December 11, 2014Publication date: April 2, 2015Inventors: David Fletcher, Brian M.

Publication number: 20140197345Abstract: Piston actuators and methods of its operation are described. The piston actuators include a housing defining a chamber having a piston therein and a spring seated against the piston to bias it into a starting position. The piston includes a ferromagnetic material, a magnet or both and a secondary magnet or ferromagnetic material, forming a first magnetic/ferromagnetic pair with the piston, is positioned to maintain the piston in a secondary position. A tertiary magnet or ferromagnetic material, forming a second magnetic/ferromagnetic pair with the piston, may assist the spring in maintaining the piston in the starting position. During operation, introduction into or removal from the chamber of an amount of fluid sufficient to overcome the force of the spring (and the tertiary magnet or ferromagnetic material) enables the attraction between the members of the first magnetic/ferromagnetic pair to move the piston to the secondary position as a snap movement.Type: ApplicationFiled: January 14, 2014Publication date: July 17, 2014Applicant: Dayco IP Holdings, LLCInventors: Brian M.
