Patent number: 10871237Abstract: A dual stage pressure relief valve for relieving pressure. The pressure relief valve includes a main body, a poppet bulb, a pilot piston, and a poppet cap. The main body defines a main channel that extends from a first opening to a second opening. The poppet bulb defines a first flow channel being in fluid communication with the main channel. The pilot piston defines a reset channel in fluid communication with the first flow channel of the poppet bulb. The cap channel has a diameter that is greater than a diameter of the reset channel. The poppet cap defines a cap channel in fluid communication with the reset channel of the pilot piston and with a pressure cavity defined by the poppet cap and an end of the main body.Type: GrantFiled: August 10, 2018Date of Patent: December 22, 2020Assignee: OATEY CO.Inventors: Marthinus Cornelius van Schoor, Attila Jozsef Lengyel, Luke Clovis Saindon, Nicholas Burnell

Patent number: 9180326Abstract: A sprinkler head including a sprinkler body with a passage for fluid and a seal mechanism sealing the passage, and a cage member. A frangible bulb extends between the cage member and the seal. A shape memory alloy element is associated with the frangible bulb and has a first configuration that fits within, about, or abutting the bulb and a second configuration at a predetermined temperature which breaks the frangible bulb releasing the fluid through the passage.Type: GrantFiled: March 12, 2009Date of Patent: November 10, 2015Assignee: Mide Technology CorporationInventors: Marthinus Cornelius Van Schoor, Attila Jozsef Lengyel, Matthew Pike
