Pressure Actuated Movable Head For A Resonant Reciprocating Compressor Balance Chamber

View page
US Patent:
48367575, Jun 6, 1989
Filed:
Jun 13, 1988
Appl. No.:
7/206220
Inventors:
Peter W. Curwen - Ballston Spa NY
Ralph Hurst - Clifton Park NY
Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
F04B 3100
US Classification:
417416
Abstract:
The present invention relates to a resonant piston compressor in which a double-sided piston reciprocates within a cylinder and defines a valved compression space on one side of the piston and a balance chamber on its other side. The invention further includes a movable head adjustable between first and second positions to effect a large change in the total volume of the balance chamber between the two positions. In one position, of the movable head an extended balance chamber volume is coupled to the balanced chamber while in the other position of the movable head, the extended balance chamber volume is decoupled from the balance chamber.

Resonant Piston Compressor Having Improved Stroke Control For Load-Following Electric Heat Pumps And The Like

US Patent:
43532209, Oct 12, 1982
Filed:
Jun 17, 1980
Appl. No.:
6/160429
Inventors:
Peter W. Curwen - Ballston Spa NY
Richard A. Dorman - Troy NY
Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
F04B 4906
F25B 4104
US Classification:
62228
Abstract:
A method and apparatus for controlling a resonant piston compressor of the type comprising an electrodynamic linear reciprocating motor adapted to be driven cyclically by an alternating current power source and having at least one piston coupled to and adapted to be driven within a selectively valved working cylinder by the linear reciprocating motor in synchronism with the frequency of the alternating current power source. Enclosed volumes of gas act as resilient gas springs coacting with the piston and with the linear reciprocating motor to form a mechanical resonant system having a resonant frequency substantially centered on the frequency of the alternating current power source. A midstroke porting arrangement is responsive to the position of the resonant piston for selectively communicating a gas spring control valve with said gas springs. The invention operates to variably control with the gas spring control valve the pressure of the gas in the gas springs to thereby dynamically modulate the stiffness of the resilient gas spring in a manner to control the stroke of the resonant piston compressor within predetermined safe limits.

Flat Plunger Linear Electrodynamic Machine

US Patent:
48146501, Mar 21, 1989
Filed:
Mar 10, 1987
Appl. No.:
7/024242
Inventors:
Peter W. Curwen - Ballston Spa NY
Ralph Hurst - Clifton Park NY
Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
F04B 2502
H02K 700
H02K 3300
US Classification:
310 22
Abstract:
An electrodynamic motor having a flat plunger core arrangement formed out of alternating layers of magnetic and insulating strips clamped together and maintained on respective bearing sleeves which reciprocate on guide members with the gap between stator members.

Linear Resonant Reciprocating Machines

View page
US Patent:
47815469, Nov 1, 1988
Filed:
Mar 10, 1987
Appl. No.:
7/024258
Inventors:
Peter W. Curwen - Ballston Spa NY
Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
F04B 3100
US Classification:
417417
Abstract:
A free-piston reciprocating compressor includes a reciprocating piston disposed within a cylinder such that one end of the piston-cylinder provides for a compression space and the other end of the piston-cylinder provides for a balancing space. The piston is coupled to and reciprocatingly driven by the armature of a linear electrodynamic motor, which armature reciprocates on guide means. The compressor also includes porting means operative to establish a stabilizing gradient sufficient to keep the piston operating at a related fixed mid-stroke position. The motor armature is also coupled to a centering-resonance spring.

Suspension And Vibration Isolation System For A Linear Reciprocating Machine

View page
US Patent:
43600875, Nov 23, 1982
Filed:
May 27, 1980
Appl. No.:
6/153839
Inventors:
Peter Curwen - Ballston Spa NY
Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
F16F 710
US Classification:
188379
Abstract:
A suspension system for a linear reciprocating machine incorporates dynamic vibration isolation means into a mass flow system of the machine. An antiphase mass movement results in an essentially zero transmissibility of machine vibration to an outer casing enclosing the machine.

Pressure Actuated Movable Head For A Resonant Reciprocating Compressor Balance Chamber

View page
US Patent:
47508701, Jun 14, 1988
Filed:
Feb 13, 1987
Appl. No.:
7/014444
Inventors:
Peter W. Curwen - Ballston Spa NY
Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
F04B 3100
US Classification:
417416
Abstract:
In a resonant piston compressor utilizing a balance chamber to provide a gas spring effect for use in a heat pump arrangement and the like, an adjustable balance cylinder head which adjusts so as to increase or decrease the balance chamber volume so as to increase or decrease the stiffness of the balance chamber, depending upon the mode of operation desired.
