A further bevelled cam projection 12 is disposed on the upper edge of the spring housing 2. Figure 5a shows a locking member 15 whose prestressed arcuate portions 16 initially press against the outer peripheral surface of the output drive member 5. Lenses with a low chromatic aberration or systems, which can correct these aberrations, will lead to good image quality as mentioned. An energy storage means, such as a spring, is preferably manually loaded e. Pressing the release button 7 causes the annular locking member to be pushed back perpendicularly to the axis of the housing whereby the path of movement of the output drive member is cleared. The compression spring pushes the output drive member upwardly over a predetermined distance and in so doing actuates a component not shown which is connected to the output drive member, for example a piston in a cylinder.

Rotation of the two housing portions relative to each other causes the mechanism to go from the condition shown in Figure la into the condition shown in Figure Ib.
A locking stressing mechanism having a longitudinal axis in a vertical direction for a spring-actuated output drive device, the mechanism comprising: In the case of a screw-type thrust transmission means the collar of the cup-shaped output drive member generally includes two sawtooth-shaped recesses against which two saw teeth in the upper housing portion slide.
It comprises functional elements which have a low rate of wear and it is reliable in operation.

The output member is arranged to move a piston in a cylinder to compress fluid therein. For that purpose the output drive flange is displaced by an axially operative external force. One aim of the invention is to adapt such a locking stressing mechanism to the requirements of a miniaturised high-pressure producing device.
Disposed in the spring housing 2 is the compression spring 4 which is kondtruktionselemente already prestressed when the two housing portions are fitted together. Full Text The invention concerns a locking latchable stressing loading mechanism for a spring-actuated output drive device and is particularly, though not exclusively, concerned with such a device by which a high pressure is produced in a fluid for example by means of a piston in a cylinder.
The travel of fwinmechanik output drive member is precisely delimited by defined abutments. The mechanism is part of a device for spraying fluid or, more specifically, part of a metered dose inhaler. A mechanism as claimed in claim 1 to 2, wherein the force step-up transmission means comprises a screw thrust transmission means provided between the drive for stressing the spring and the spring.
Accordingly to the present invention, there is provided a locking stressing mechanism having a longitudinal axis in a vertical direction for a spring-actuated output drive device, the mechanism comprising: When the release button is actuated the locking member is pushed back into the disengaged position and the path of movement of the output drive member is cleared.
The compression spring 4 is supported konstruktionzelemente a peripherally extending projection konstruktiinselemente the lower end of the spring housing and on konstrultionselemente output drive member 5 which is arranged displaceably in axis-parallel relationship between the upper housing portion and the spring housing and which in turn presses against the upper housing portion 1.
Konstruktionselemente der Feinmechanik
Konstruktionselemente der Feinmechanik, Verlag Carl Hanser, Munichpages to previously stored energy is liberated at the required moment and converted into movement. Konstruktionselemente der Feinmechanik Werner Krause. As soon as the upper edge of the output drive member has been pressed through the locking member the projections 20 jump over the upper edge of the output drive member into the engaged position.
The transmission comprises a rotatable part with a sawtooth thrust cam. When the release button is actuated the arcuate portions 16, by virtue of their bending loading, are urged outwardly and clear the way for displacement of the output drive member. It is compact and can easily be adapted to a miniaturised high-pressure atomiser.
The metering effect is very accurate because of the defined abutments for the output drive member. A projection 20 is disposed on the inside of each spring portion. A locking stressing mechanism as just described with reference to the drawings has konstuktionselemente following advantages: According to another aspect of the invention, there is provided a spring-loaded drive mechanism in which an output member is mounted for linear movement against the bias of a spring between a released position and feinmechznik locked position and in which there is a locking member which can be moved transversely deg the direction of kkonstruktionselemente of the output member into and out of the path of an abutment means associated with the output member, wherein the locking member is substantially in the form of an open or closed ring such that the abutment means can pass through it under the action of the spring when the mechanism is released and wherein the substantially ring-like locking member may optionally be in two or more sections.

When the upper housing portion is rotated relative to the spring housing the output drive member is urged further into the spring housing against the force of the compression spring. Although the book is an assemblage of parts written by different authors, the overall uniformity of the work is commendable and the readability is good.
This is realized by moving the image sensor with a very high precision. Any further distribution of this work must maintain attribution to the author s and the title of the work, journal citation and DOI.
The locking member is resiliently deformable so as to provide the snap action. Bloggat om Contrast Agents I. In 2,4,6-triiodobenzoic acid derivatives iodine is firmly bound. The feinmechanok member snaps into alignment with the abutment means when the output member reaches the locked position. The locking stressing mechanism comprises a force step-up transmission means, for example a screw thrust transmission means, for stressing the spring, an annularly arranged locking member with engaging locking surfaces, two abutments for limiting the travel of the spring and a release button.
Towards the end of the rotary movement of the upper housing portion relative to the spring housing the two cam projections come to bear against each other with their bevelled sides and the cam feinmecyanik on the spring housing pushes the locking member 10 konstruktionselrmente the engaged position.
One part of all spectral imaging systems is the optical system beside illumination and sensor characteristics.
