Abstract: A system is disclosed for cleaning the interiors of tubes in heat exchangers such as condensers and other devices having numerous substantially parallel tubes which periodically become fouled, scaled, or otherwise encumbered with deposits. An air-actuated seal resides on the end of a nozzle which is projected into the open end of a condenser tube or other heat exchanger tube to be cleaned. An air cylinder and piston retract the end of the nozzle on actuation of a single trigger valve on a manually operated water gun, which both begins high pressure water flow and operates the piston. On actuation of the trigger valve, the segment of the nozzle which has been inserted is retracted a short distance, crimping a flexible sleeve which surrounds it into a tight seal on the inner surface of the tube, thus preventing backflow or back spray.

Abstract: A manual reset actuator is disclosed, which includes a main drain, a diaphragm release aperture fluidly coupled to a flow control valve, an upper chamber, a control port, a control orifice, an upper chamber supply orifice, and a sealing assembly, which includes a button, and a plunger. A pressure in the upper chamber exerts a downward force on the plunger. A spring exerts an upward force on the plunger. The fluid in the upper chamber is released via the control orifice, which lowers the pressure in the upper chamber, decreasing the downward force exerted on the plunger. When the downward force is less than the upward force, the spring forces the plunger upwards into an open configuration, which unseals the diaphragm release aperture. When the upward force is less than the downward force, the plunger remains in a closed configuration, which keeps the diaphragm release aperture sealed.

The medium is charged into the first channel at opposite sides of the second body. The thermal element is proximate to the first channel and is operable to cause the medium to drive movements of the second body to the first or the second positions.
