摘要： The disclosure relates to a device and a method for controlling the throughflow of blow-molding fluid during the blow molding of containers. It is the intention to provide a control device and a control method which permit a controlled or defined growth and a defined propagation of the container bubble formed by the expanding preform in the pre-blowing phase of the blow molding process without the specification of a specific setpoint value profile or of a setpoint value curve. The object is achieved by means of a control device and a control method having a proportional valve with a variable throughflow cross section, having an actuator for the operation of the proportional valve, having a means for detecting the position of the actuator, and having sensor means for detecting the valve inlet and valve outlet pressure, wherein a time for the attainment of the yield point for the preform, a container volume and a time period for the attainment of the container volume are predefinable, and, by means of a digital controller, during the pre-blowing phase, from the attainment of the yield point until the run duration, a calculation of control values for the operation of the actuator in order to attain the predefined container volume within the predefined time period is performed in automated cyclic fashion, and the actuator is operated in accordance with the calculated control values, wherein, in each calculation cycle, the calculation of the respectively next control value is performed taking into consideration the container volume attained prior to the respective calculation cycle and calculated on the basis of the previous actuator positions and the previous pressure profile.

摘要： The disclosure relates to a diaphragm poppet valve. The intention is to provide a diaphragm valve which is constructed as simply as possible with few components and with valve parts through which a working fluid flows that are easy to clean. The problem is solved by a diaphragm poppet valve with a control diaphragm which is resilient in shape and separates a control chamber from a working chamber, wherein the control diaphragm is designed as a single piece on the side thereof facing the control chamber or the working chamber of the diaphragm poppet valve with a hollow portion and on the side thereof facing the working chamber with a diaphragm valve seat, wherein the interior of the hollow portion issues into the diaphragm valve seat and the hollow portion is connected to a fluid channel in the diaphragm poppet valve. The diaphragm poppet valve according to the disclosure is easy to clean because the interior of the hollow projection and the diaphragm valve seat formed by the control diaphragm can easily be flushed. In addition, the number of components is reduced by integrating a valve seat immediately into the control diaphragm itself. At the same time, dead spaces are avoided by integrating a hollow projection which can be connected to a fluid channel.

摘要： The disclosure relates to a pneumatic control system for a working cylinder, which pneumatic control system enables resistance-free manual motion of the device driven by the working cylinder in the event of a failure or switch-off of the compressed air supply and is independent of electrical supply. The problem is solved by means of a pneumatic control system having a double-acting working cylinder, the two chambers of which can be connected oppositely to a compressed air source and a compressed air outlet by means of a controllable supply device having two operating positions, an independently resetting 3/2-way valve switchable by means of a control pressure being arranged before each chamber in a connecting line to the supply device, which 3/2-way valves connect the chambers to bleeding outlets in a first switching position and to the supply device in a second switching position, and a parallel circuit of a check valve and a throttle point being arranged before each chamber, the check valves of which parallel circuits block in the backflow direction, wherein the two 3/2-way valves assume the first switching position in the idle position and can be switched by means of a common control line, which is connected to both connecting lines to the supply device downstream of the 3/2-way valves by means of a changeover valve, and the parallel circuits are arranged in the connecting lines downstream of the respective 3/2-way valves.

摘要： A braking-stopping unit for the defined stopping and braking of a manually operable command issuer for ship's drives includes an external rotor with a circular opening forming a bearing ring and an inner rotor arranged in the opening, which are arranged in a rotationally movable manner relative to each other. One of the two rotor elements is statically fixed in its position and the other rotor element is designed either with a manually operable actuator or constructed so as to be connectable to such an actuator. The inner rotor includes at least three spring arms which are radially arranged in the circumferential direction, wherein said spring arms can be pushed into a respective recess arranged in the outer surface of the inner rotor. The spring arms act in each case radially non-positively on the running surface of the bearing ring via the braking and stopping means.

摘要： A valve assembly includes a proportional valve having an opening cross section that can be continuously varied by an actuator; a sensor for sensing the valve output pressure; a digital regulating device; and a switching valve disposed parallel to the proportional valve. The opening cross section of the switching valve is smaller than the maximum opening cross section of the proportional valve. The regulating device is programmed (i) to automatically calculate, at runtime, using the currently given valve output pressure and the current position of the actuator, the maximum working pressure achievable at the maximum opening of the proportional valve with the valve, (ii) and to additionally open the switching valve when the computed maximum achievable working pressure falls below a predefinable target working pressure by a definable deviation value.

摘要： The disclosure relates to a sealing diaphragm and a check valve comprising a sealing diaphragm for fluid technology applications. A sealing diaphragm for fluid technology applications is to be provided, which is economical and constructionally simple to produce, which can be used as a closing means for a check valve and with which unwanted interfering noise can be prevented during operation. The object of the disclosure is achieved by a sealing diaphragm with a flat, flexible sealing section, which can be bent or curved with a fluid pressure, wherein at least one resilient frictional tooth is provided on or next to the surface of the sealing section at a distance from an edge of the sealing section, designed and arranged in such a way that it forms an angle between 30° and 150° with the sealing section and it tilts together with the bending or curving movement of the flat sealing section, wherein the frictional tooth has a contact surface on a side orientated in the tilting direction. The object of the disclosure is also achieved by a check valve for fluid technology outlet openings, comprising a housing part having a fluid outlet, wherein an above-mentioned sealing diaphragm is arranged in the flow path of the outlet opening, which is in contact with a sealing surface of a seal seat with a sealing section against the direction of flow and which can be bent or curved with a fluid pressure in the flow direction, wherein the contact surface of the at least one frictional tooth is simultaneously in contact with a corresponding bearing surface.
