Patent number: 10107408Abstract: A temperature response valve is disclosed. The valve has a body with an outside surface and an outlet. The valve has a sleeve that partly engages the outside surface of the valve body to direct, via channels on an inner surface of the sleeve, water flowing out of the valve body outlet. The water is held into contact with part of the outer surface and expelled at a removed end of the sleeves where the channels open to the environment. The valve engages the threads on a threaded male member of an outside faucet.Type: GrantFiled: February 28, 2017Date of Patent: October 23, 2018Assignee: BAKER PRODUCTS, LTD.Inventor: Robert Dulin

Patent number: 9822886Abstract: In a valve having a body with a sealed working fluid chamber, a bore and a valved fluid chamber, the valved fluid chamber having an inlet and outlet and a seat between the inlet and the outlet, a piston for extending through the bore from the working fluid chamber to the valved fluid chamber, a spring for biasing the piston away from the seat and a working fluid for receipt in the working fluid chamber. Applicant provides an improvement comprising a seal stack assembly for entrainment, under compression, upon the piston and in the piston chamber between a working fluid chamber end wall and a first end of the piston, wherein the first end of the piston is located in the working fluid chamber and a second end in the valved fluid chamber.Type: GrantFiled: October 15, 2015Date of Patent: November 21, 2017Assignee: Baker Products, Ltd.Inventor: Robert Dulin

Patent number: 9482357Abstract: Applicant discloses a thermally actuated valve having a housing, a resilient seat, a thermally conductive piston, a spring fluid seal, and a working material. The housing defines an inlet and an outlet and has two chambers. The seat is adjacent the inlet and the piston is adapted to move towards the seat when a working fluid in the housing warms and expands and away from the seat when a working fluid in the housing cools. By moving away from the seat, fluid flow through the valve is generated. In one application, Applicant's valve acts as a freeze prevention device. In another application, Applicant's valve is used to cool a source of water.Type: GrantFiled: October 29, 2013Date of Patent: November 1, 2016Assignee: Baker Products Ltd.Inventor: Robert Dulin

Patent number: 8827237Abstract: A fluid flow valve is disclosed which includes a fluid flow assembly, a piston diaphragm assembly, and a reset plunger pin assembly. These three assemblies are configured to engage one another such that, when used in conjunction with a pressurized water source, they will split the pressurized water source into two portions, the one portion defining a main fluid flow pathway through the valve and, a much smaller proportion, defining a metered fluid flow pathway through the valve. The piston diaphragm assembly has a diaphragm or other equivalent structure for defining a metered fluid flow chamber, which metered fluid flow chamber is fluidly engaged to a pressurized water source through a metering channel in a piston. A reset plunger meter pin assembly engages the metered fluid flow or piston chamber of the piston diaphragm assembly and can initiate a timed flow of water or other fluid into the metered fluid flow chamber, which timed flow controls the flow of fluid or water flowing through the fill valve.Type: GrantFiled: May 4, 2011Date of Patent: September 9, 2014Assignee: Baker Products, Ltd.Inventor: Robert Dulin

Publication number: 20060249590Abstract: A temperature sensitive valve is disclosed herein. The valve has a piston, thermal sensor containing a thermally sensitive material, and biasing element. The thermal sensor is in contact with the surrounding fluid so that thermal material contracts in ambient temperatures, allowing the valve to open. With the valve open, the surrounding fluid is replaced by warmer fluid, heating the thermal material causing it to expand and the thermal sensor close off flow through the valve.Type: ApplicationFiled: September 12, 2005Publication date: November 9, 2006Inventor: Robert Dulin

Publication number: 20050199296Abstract: An adaptive fitting for valves. The adaptive fitting has a fitting body having a first end and a second end. The fitting body defines an inner passageway extending from the first end of the fitting to the second end. The fitting is provided with a valve-engaging portion disposed on the first end of the fitting body. This valve-engaging portion has a threaded region for threadably engaging a threaded section of a valve. On the second end of the fitting body is disposed a sealing portion. The fitting is provided with one or more ports disposed about or near the first end of the fitting body for allowing flow there through.Type: ApplicationFiled: March 10, 2004Publication date: September 15, 2005Inventor: Robert Dulin
