  • Hydraulic heater valve
    Patent number: 8881992
    Abstract: Provided is a valve assembly having a thermal valve member and a priority valve member that are shiftable to first and second positions in response to a temperature and pressure of a fluid flowing through the valve assembly. Consequently, the valve can provide for flow through a heating orifice under low temperature, high pressure conditions so that pressure drops in fluid lines coupled to the valve assembly may be prevented or reduced, allowing fluid lines with small diameters to be used in an aircraft or other fluid flow system, thereby reducing the weight of the aircraft or fluid flow system.
    Type: Grant
    Filed: March 28, 2011
    Date of Patent: November 11, 2014
    Assignee: Parker-Hannifin Corporation
