Patent number: 9599243Abstract: A pressure relief valve having a housing with an inlet port, an outlet port and a curvilinearly extending housing interior sidewall that defines a flow passageway through the housing from the inlet port to the outlet port. A piston assembly that is moveable between a closed position to establish a fluid-tight seal between the inlet port and the outlet port, and an open position to permit fluidic flow of pressurized fluid from the inlet port to the outlet port. The piston assembly has a piston head having a parabolically shaped piston face and elliptical perimeter that, when the inlet piston assembly is moved to the open position, aligns with the housing interior sidewall to provide a continuous transition from a position immediately upstream of the piston to a position immediately downstream of the piston.Type: GrantFiled: August 21, 2015Date of Patent: March 21, 2017Assignee: Taylor Innovations, LLCInventors: Julian S.

Patent number: 9599245Abstract: A two-stage, variable force, solenoid control valve for regulating fluid pressure can include a valve body having a pilot fluid passage, including a metering land, in fluid communication with a flow amplifying fluid passage through a valve control port formed in the valve body. A solenoid operated pilot valve member, disposed in the pilot fluid passage can have a metering orifice operable in combination with the metering land for selectively connecting the valve control port with a pressurized fluid supply port and a return exhaust port in response to activation of a solenoid. A flow amplifying spool valve member, in fluid communication with the valve control port of the pilot valve member at one end, can selectively connect a load control port with the pressurized fluid supply port and the return exhaust port in response to pilot valve member operation.Type: GrantFiled: February 24, 2012Date of Patent: March 21, 2017Assignee: BORGWARNER INC.Inventor: Garrett R.

Patent number: 9599246Abstract: A latching solenoid gate valve includes a housing defining a conduit having a flow path therethrough and a cavity separating the conduit into a first section and a second section. The latching solenoid assembly also includes a gate assembly enclosed within the cavity of the housing and a first solenoid assembly and a second solenoid assembly seated within the cavity with the gate assembly linearly translatable therebetween. The gate assembly includes a first gate member comprising magnetizable material and defining an opening therethrough. The first gate member is linearly movable within the cavity between an open position with the opening aligned with the conduit and a closed position with the opening out of alignment with the conduit. The first gate member is moved linearly from either the open position or the closed position.Type: GrantFiled: August 5, 2015Date of Patent: March 21, 2017Assignee: DAYCO IP HOLDINGS, LLCInventors: David E. Fletcher, Brian M. Graichen, James H. Miller, Keith Hampton

Patent number: 9599247Abstract: An electromagnetic valve for controlling the flow of a pressure medium, said electromagnetic valve comprising a valve housing with an inlet port and an outlet port for the pressure medium; at least one passage opening, which connects the inlet port to the outlet port, for the pressure medium; a valve slide that can be moved axially between a first basic position, which closes the passage opening, and a second basic position, which opens the passage opening, by means of a solenoid coil; and a spring assembly, which positions the valve slide in the first or the second basic position when the solenoid coil is not energized. A spring excursion limiting means limits a specified spring excursion of the second spring portion to position the valve slide in an intermediate position between the first and second basic position by the energized solenoid coil. The valve slide releases at least a partial cross section of the passage opening in the intermediate position.Type: GrantFiled: June 3, 2014Date of Patent: March 21, 2017Assignee: KENDRION (VILLINGEN) GMBHInventors: Joachim Flühs, Holger Brandenburg
