Patent number: 10295075Abstract: A cylinder valve for use with a cylinder containing fluid under pressure. The cylinder valve has an aluminum valve body. The valve body has a flow passage extending through the valve body for permitting fluid to flow through the body to exit the cylinder and a vent passage for permitting fluid to vent from the cylinder. Nickel plating is applied to the vent passage. A dispensing valve is positioned along the flow passage. Thermal relief material in the vent passage blocks flow through the vent passage until a predetermined venting temperature is reached when the material changes to a flowable state to unblock the vent passage and allow venting of the cylinder through the vent passage.Type: GrantFiled: January 10, 2017Date of Patent: May 21, 2019Assignee: Control Devices, LLCInventor: Daniel A. Lammers

Publication number: 20150013776Abstract: A regulating valve includes a regulating-valve-high-pressure connector, a regulating-valve-low-pressure connector, and a regulating-valve-pressure-reducing device. The regulating-valve-pressure-reducing device includes a regulating-valve-high-pressure chamber coupled to the regulating-valve-high-pressure connector, a regulating-valve-low-pressure chamber coupled to the regulating-valve-low-pressure connector, and a regulating-valve-high-pressure regulator coupled to the regulating-valve-high-pressure chamber and the regulating-valve-low-pressure chamber to maintain the regulating-valve-low-pressure chamber at a constant pressure. The regulating valve further includes a pressure gauge coupled to the regulating-valve-low-pressure chamber.Type: ApplicationFiled: July 15, 2013Publication date: January 15, 2015Inventor: Daniel A.

Patent number: 8327868Abstract: A cylinder valve for use with a cylinder containing fluid under pressure includes a valve body configured for releasable connection to the cylinder. The valve body has a flow passage extending through the valve body for fluid communication with an interior of the cylinder when the valve body is connected to the cylinder. A valve in the flow passage is movable between open and closed positions. A vent passage is in the valve body and is separate from the flow passage. A temperature relief insert is in the vent passage. The insert includes an insert body, a bore through the insert body, and a thermal relief material in the bore blocking flow through the bore until a predetermined venting temperature is reached. The valve body does not contain brass and the insert body is brass covered by a metal plating not containing brass.Type: GrantFiled: June 4, 2009Date of Patent: December 11, 2012Assignee: Control Devices, LLCInventor: Daniel A. Lammers

Patent number: 7159797Abstract: A spray head for discharging fluid includes a turret assembly in which a nozzle carrier is rotatable relative to a housing about an axis, and a plurality of nozzles mounted on the carrier radially outward from the axis. The carrier is mounted for linear movement relative to the housing along the carrier axis from a retracted position in which one of the nozzles is mated with an outlet in the housing for discharging fluid, to an extended position in which the carrier is rotatable about the carrier axis to align a different nozzle with the outlet, and back to the retracted position in which the different nozzle is mated with the outlet. A latch on the housing is moveable radially with respect to the carrier axis between a latching position holding the carrier in the retracted position and a release position allowing the carrier to move to the extended position.Type: GrantFiled: June 20, 2006Date of Patent: January 9, 2007Assignee: Control Devices, Inc.Inventor: Daniel A. Lammers

Patent number: 6866062Abstract: A check valve for a compressed gas system. The valve has a body with an internal passage extending through the body and a valve seat positioned in the passage. A poppet is movable between a closed position in which the poppet engages the seat to block flow of gas through the passage and an open position in which the poppet is spaced from the seat to permit flow of gas. A retainer mounts the poppet in the passage and guides movement of the poppet. A spring urges the poppet to the closed position such that the poppet is responsive to pressure of the gas exceeding a predetermined value to move the poppet away from the seat against the urging of the biasing member and to the open position.Type: GrantFiled: September 10, 2002Date of Patent: March 15, 2005Assignee: Control Devices, IncorporatedInventor: Daniel A. Lammers

Patent number: 5967410Abstract: A thermal relief valve to be mounted in a fluid flow line. The valve comprises a valve body and a valve actuator movable in a bore defined by a bore wall in the valve body from a sealing position in which the actuator sealingly engages a valve seat to block flow through the valve to a non-sealing position. The valve actuator is responsive to the temperature of the fluid exceeding a predetermined temperature to move to its non-sealing position. The relief valve has an actuator body configured to have first exterior surfaces sized for a close clearance fit with the bore wall at spaced locations around the actuator body to prevent substantial lateral shifting of the body relative to the bore wall, and second exterior surfaces which extend between the first exterior surfaces and which are spaced farther from the bore wall to define flow passages to permit the flow of fluid past the actuator when the valve actuator moves to its non-sealing position.Type: GrantFiled: December 30, 1998Date of Patent: October 19, 1999Assignee: Control Devices, IncorporatedInventor: Daniel A.
