Abstract
Abstract A baffle plate between two opposing nozzles is mounted on a flexible carrier which is secured to the armature of an electromagnet so that energization of the electromagnet by control signals causes variations of the throttle gaps between the nozzles and the baffle plate which causes a pressure differential between the discharge conduits of the nozzles. The discharge conduits communicate with chambers of a control slide valve which responds to the pressure differential. The pole shoes of the electromagnet are adjustable toward and away from the armature, and the nozzles are adjustable toward and away from the baffle plate so that irregular tolerances and outer influences on the control system can be compensated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
Regulating apparatus with throttle gaps, comprising electromagnetic means including a magnet having at least two opposite pole shoes, and a movable armature between said pole shoes magnetically cooperating with, and being moved by said pole shoes; adjusting means for adjusting said pole shoes independently of each other toward and away from each other for varying the distance between said pole shoes and thereby the flux therebetween and through said armature; at least one baffle plate connected with said armature for movement; a pair of nozzles having discharge conduits and located on opposite sides of said baffle plate forming throttle gaps with the same so that displacement of said baffle plate by said armature causes variations of said throttle gaps and a pressure differential between said discharge conduits; and control valve means communicating with said discharge conduits and being operated in accordance with said pressure differentiAl.
Claim 2
Dependent Claim
145 words
Regulating apparatus with throttle gaps, comprising electromagnetic means including a magnet having at least two opposite pole shoes, and a movable armature between said pole shoes magnetically cooperating with, and being moved by said pole shoes; adjusting means for adjusting said pole shoes independently of each other toward and away from each other for varying the distance between said pole shoes and thereby the flux therebetween and through said armature; at least one baffle plate connected with said armature for movement; a pair of nozzles having discharge conduits and located on opposite sides of said baffle plate forming throttle gaps with the same so that displacement of said baffle plate by said armature causes variations of said throttle gaps and a pressure differential between said discharge conduits; and control valve means communicating with said discharge conduits and being operated in accordance with said pressure differentiAl.
Claim 3
Dependent Claim
47 words
An apparatus as claimed in claim 1 wherein said adjustable pole shoes are located on the same side of said armature; and wherein said magnet is permanent and includes two other pole shoes located on the other side of said armature respectively opposite said adjustable pole shoes.
Claim 4
Dependent Claim
105 words
An apparatus as claimed in claim 1 comprising a carrier secured to said armature and said baffle plate and supporting the same for angular movement, said carrier having a rigid end portion, and a flexible elastic portion adjacent the other end thereof; an wherein said baffle plate and said armature are secured to said other end of said carrier, said armature having a hub portion surrounding said rigid end portion, whereby displacement of said armature causes elastic bending of said flexible portion and angular displacement of said baffle plate toward one of said nozzles and away from the other nozzle of said pair of nozzles.
Claim 5
Dependent Claim
38 words
An apparatus as claimed in claim 3 wherein said flexible portion bends about an axis located at the center of gravity of the combined mass of said armature, said baffle plate, and said other end of said carrier.
Claim 6
Dependent Claim
50 words
An apparatus as claimed in claim 1 wherein said control valve means include a valve cylinder and a valve slide in the same; comprising a housing for said valve cylinder made of a titanium alloy; and sealing means for sealing said valve cylinder in said housing and consisting of metal.
Claim 7
Dependent Claim
21 words
An apparatus as claimed in claim 1, wherein said magnet has threaded bores into which said pole shoes are adjustably threaded.
Claim 8
Dependent Claim
209 words
Regulating apparatus with throttle gaps, comprising electromagnetic means including a magnet having at least two pole shoes, and a movable armature magnetically cooperating with said pole shoes and moved by the same, said magnet having two pairs of threaded bores located on opposite sides of said armature; said adjustable pole shoes being adjustably threaded into one pair of said bores located on the same side of said armature; first adjusting means for threading said adjustable pole shoes in said threaded bores independently of each other toward and away from said armature, and two other pole shoes located on the other side of said armature and threaded into the other pair of bores; at least one baffle plate connected with said armature for movement; a pair of nozzles having discharge conduits located on opposite sides of said baffle plate forming throttle gaps with the same so that displacement of said baffle plate by said armature causes variations of said throttle gaps and a pressure differential between said discharge conduits; second adjusting means for adjusting said nozzles toward and away from said baffle plate and for varying the throttle gaps; and control valve means communicating with said discharge conduits and being operated in accordance with said pressure differential between the same.
Claim 9
Dependent Claim
209 words
Regulating apparatus with throttle gaps, comprising electromagnetic means including a magnet having at least two pole shoes, and a movable armature magnetically cooperating with said pole shoes and moved by the same, said magnet having two pairs of threaded bores located on opposite sides of said armature; said adjustable pole shoes being adjustably threaded into one pair of said bores located on the same side of said armature; first adjusting means for threading said adjustable pole shoes in said threaded bores independently of each other toward and away from said armature, and two other pole shoes located on the other side of said armature and threaded into the other pair of bores; at least one baffle plate connected with said armature for movement; a pair of nozzles having discharge conduits located on opposite sides of said baffle plate forming throttle gaps with the same so that displacement of said baffle plate by said armature causes variations of said throttle gaps and a pressure differential between said discharge conduits; second adjusting means for adjusting said nozzles toward and away from said baffle plate and for varying the throttle gaps; and control valve means communicating with said discharge conduits and being operated in accordance with said pressure differential between the same.
Claim 10
Dependent Claim
