Patent number: 9617988Abstract: Embodiments of the invention provide a system, method and computer program product for reducing the hold-up volume of a pump. More particularly, embodiments of the invention can determine, prior to dispensing a fluid, a position for a diaphragm in a chamber to reduce a hold-up volume at a dispense pump and/or a feed pump. This variable home position of the diaphragm can be determined based on a set of factors affecting a dispense operation. Example factors may include a dispense volume and an error volume. The home position for the diaphragm can be selected such that the volume of the chamber at the dispense pump and/or feed pump contains sufficient fluid to perform the various steps of a dispense cycle while minimizing the hold-up volume. Additionally, the home position of the diaphragm can be selected to optimize the effective range of positive displacement.Type: GrantFiled: August 22, 2014Date of Patent: April 11, 2017Assignee: Entegris, Inc.Inventors: Marc Laverdiere, James Cedrone, George Gonnella, Iraj Gashgaee, Paul Magoon, Timothy J.

Patent number: 8430120Abstract: A proportional fluid control valve with improved linearity and reduced hysteresis is disclosed. The valve allows for smooth, gentle flow of fluid in a substantially linear fashion, with minimal turns. Preferably the valve is pneumatically actuated. Where temperature is not an issue, the valve can be actuated by any suitable means, including stepper motors, linear motors, voice coils or other force actuators. A versatile molded valve body that requires fewer parts compared to a machined valve is disclosed. In one embodiment, the molded valve body is designed specifically for flow control and contains two sensor housings with carefully positioned flow paths to optimize the use of space. The sensor housing or housings can be separately formed as inserts, allowing installation in various orientations.Type: GrantFiled: November 21, 2011Date of Patent: April 30, 2013Assignee: Entegris, Inc.Inventors: Marc Laverdiere, Robert F.
