Solenoid Valve

US Patent:
6505812, Jan 14, 2003
Filed:
Nov 17, 2000
Appl. No.:
09/715890
Inventors:
Jeffrey V. Anastas - Kennebunk ME
Assignee:
MKS Instruments, Inc. - Andover MA
International Classification:
F16K 3102
US Classification:
25112907, 25112915, 251282, 2513353
Abstract:
A valve assembly including a body having an inlet port, an outlet port, and a valve seat having a passageway. An electrical solenoid assembly moves a valve member upon being energized to control fluid flow between the inlet and the outlet ports. The valve assembly also includes a fluid-tight bellows positioned to apply a force to the valve member, and a pressure balancing passageway connects the inlet port to the bellows. The valve assembly further includes a housing received over the solenoid assembly and having a flange received against the valve body. A seal is positioned between the flange of the housing and the valve body, and a collar is secured in a continuous manner to the valve body over the housing flange, thereby securing the housing to the valve body and applying a sealing force to the seal in a substantially even manner.

Blade Outer Air Seal Assembly And Support

US Patent:
2012018, Jul 26, 2012
Filed:
Jan 25, 2011
Appl. No.:
13/012845
Inventors:
Anne-Marie B. Thibodeau - Sanford ME, US
Bruce E. Chick - Strafford NH, US
Thurman Carlo Dabbs - Dover NH, US
James N. Knapp - Sanford ME, US
Dmitriy A. Romanov - Wells ME, US
Russell E. Keene - Arundel ME, US
Jeffrey Vincent Anastas - Kennebunk ME, US
International Classification:
F01D 25/12, F01D 11/08
US Classification:
415 1, 4151731, 415115
Abstract:
An example blade outer air seal support assembly includes a main support member configured to support a blade outer air seal. The main support member extends generally axially between a leading edge portion and a trailing edge portion. The leading edge portion is configured to be slidably received within a groove established by the blade outer air seal. A support tab extends radially from the support member toward the blade outer air seal. The support tab is configured to contact an extension of the blade outer air seal to limit relative axial movement of the blade outer air seal. A gusset spans between the support tab and the support member. An example blade outer air seal assembly includes a blade outer air seal assembly having an inwardly facing surface. A blade path portion of the inwardly facing surface is axially aligned with a tip of a rotating blade. A peripheral portion of the inwardly facing surface is located axially in front of the blade path portion, axially behind the blade path portion, or both. The blade outer air seal assembly establishes cooling paths that terminate at a plurality of apertures established within the inwardly facing surface. The plurality of apertures are locate exclusively within the blade path portion.

Mass Flow Device Using A Flow Equalizer For Improving The Output Response

US Patent:
2008025, Oct 16, 2008
Filed:
Apr 12, 2007
Appl. No.:
11/786668
Inventors:
Junhua Ding - Tewksbury MA, US
Jeffrey Anastas - Kennebunk ME, US
International Classification:
G01F 15/00
US Classification:
73198
Abstract:
A mass flow device comprises an inlet and an outlet; a bypass and a laminar flow element disposed within the bypass. The device also includes a sensor constructed so as to provide an output signal representative of the flow rate through the mass flow device, the sensor including a tube in fluid communication with the inlet and the laminar flow element at an upstream connection location, and the outlet and the laminar flow element at a downstream connection location. A flow equalizer is disposed between the inlet and the upstream connection location, wherein the flow equalizer includes a porous medium constructed with an interconnected porosity so as to greatly reduce the flow disturbance to the sensor with an approximate equalized flow pattern exiting the equalizer.

Thermal Anemometry Mass Flow Measurement Apparatus And Method

US Patent:
6868723, Mar 22, 2005
Filed:
May 16, 2003
Appl. No.:
10/440371
Inventors:
Ali Shajii - Canton MA, US
Nicholas Eugene Kottenstette - South Bend IN, US
R. Leonard Myatt - Norfolk MA, US
Jeffrey Vincent Anastas - Kennebunk ME, US
Assignee:
MKS Instruments, Inc. - Wilmington MA
International Classification:
G01F001/66
US Classification:
7320422, 738665
Abstract:
A mass flow measurement apparatus including a flow path defined by a tubular side wall, a probe extending through the side wall into the flow path so that a first portion of the probe is located in the flow path and a second portion of the probe, extends out of the side wall, a heater element secured to the probe, and a seal preventing fluid flowing through the flow path from contacting the heater element.

Valve Assembly Having Rigid Seating Surfaces

US Patent:
7387135, Jun 17, 2008
Filed:
Dec 23, 2004
Appl. No.:
11/021912
Inventors:
Jeffrey V. Anastas - Kennebunk ME, US
Assignee:
MKS Instruments, Inc. - Wilmington MA
International Classification:
G05D 7/06, F16K 25/00
US Classification:
1374875, 1374542, 137486, 251333, 251359, 251368, 25112915
Abstract:
A valve assembly including a valve body having a bore and a port extending to the bore, an orifice member received in the bore and having an end wall and a side wall, and wherein the end wall defines an orifice providing fluid communication with the port of the body. A valve member is received in the orifice member and is movable along an axis with respect to the orifice, and a flat spring is secured to the side wall of the orifice member and has arms secured to the valve member. A valve seat is secured to the end wall and defines an opening over the orifice, and a plug is secured to an end of the valve member opposite the valve seat such that, when the valve member is moved along the axis towards the orifice, the plug contacts the seat to seal the opening.
