Patent number: 9366373Abstract: Disclosed is an absorber system for absorbing pressure shocks and fluid volume shocks in a fluid system. In particular, the absorber system includes a housing with a joint for insertion within a fluid system, wherein the housing interior is in fluid communication with fluid in the fluid system. As such, when a pressure and/or fluid volume shock is developed within the fluid system, fluid is forced into the housing via the joint. A membrane is disposed within the housing in such a way that the fluid impacts the membrane which, in response, flexes to absorb and control the pressure and/or fluid volume shock within the fluid system. The absorber system, thus, controls pressure and/or fluid volume shock within a system and can prevent water hammer and other problems which can result from the development of pressure and/or fluid volume shock.Type: GrantFiled: May 20, 2014Date of Patent: June 14, 2016Assignee: AMTROL Licensing Inc.Inventors: Christopher A.

Publication number: 20150345802Abstract: Disclosed is an expansion tank having an internal cavity separated by a flexible diaphragm to form an upper pressurized gas portion and a lower pressurized fluid portion, and an indicator positioned at an upper part of the expansion tank in communication with the contents of the upper pressurized gas portion. The indicator is configured so as to display a first color if the operating conditions are normal in the pressurized gas portion, and a second color if the amount of moisture detected in the pressurized gas portion greater than or equal to a predetermined amount. Further disclosed is a method for detecting whether there is an excessive amount of moisture in a pressurized gas portion of an expansion tank by allowing pressurized gas from the pressurized gas portion to come into contact with the indicator, and viewing the color displayed by the indicator. As such, the tank can be simply visually inspected to determine whether there is a potential failure in the tank.Type: ApplicationFiled: May 30, 2014Publication date: December 3, 2015Applicant: AMTROL Licensing Inc.Inventors: Christopher A.
