Description

 The invention relates to automation, and in particular to systems for supplying electrical, pneumatic and hydraulic commands to actuators.

 The invention provides the receipt of commands in a certain sequence and can find application in controlling various processes in various fields of technology.

 A mechanical software device (cam) is known, in which the cam mechanism serves as a setter for the program-time sequence of commands [1]. The disadvantages of the device include wear as the software cams themselves, and the contacting elements at high linear speeds.

 Also known pneumatic software device [2]. The disadvantages of this device include the fact that commands cannot be transmitted with great mechanical effort and over a long distance.

 Hybrid software devices are also known, such as electromechanical, electro-pneumatic or pneumohydraulic, characterized by the complexity of the designs and the complexity of manufacturing.

 Closest to the claimed is a multi-position software device [3], made in the form of a rotating rotor with contacting elements located along a helical line, interacting with sensors through a system of levers of the second kind.

 The disadvantages of the prototype include insufficiently high reliability of the device due to friction losses in the mechanical parts, the inability to transmit commands with great effort, the need for high accuracy and purity of processing parts and assemblies.

 The aim of the invention is the expansion of operational capabilities, improving the reliability and manufacturability.

 The goal is achieved in that in the device for program control comprising a housing, switching elements and a drive for switching them, according to the invention, the housing is made in the form of a sealed container in communication with the supply system of the working agent, a drum is placed in the container, on which one end of the elastic sleeve is wound, the other end of which is turned inside out and fixed in the container, moreover, switching elements are placed on the drum, the drum is fixed on an axis connected to a coil spring.

 The expansion of operational capabilities is achieved due to the fact that in the places of final inclusions hydraulic cylinder rods, cams, mechanical levers can be used. Significant efforts can be obtained on the switching elements.

 Improving reliability is achieved by reducing friction losses. Improving manufacturability is achieved by the fact that the nodes and parts are simple in execution, do not require high accuracy and purity in manufacturing.

 Comparison of the claimed solutions with the prototype shows that it differs in the presence of new elements and the relationships between them, which makes it possible to conclude that the claimed solutions meet the criteria of the invention of "novelty."

 Comparison of the claimed solution with other solutions known in science and technology shows that it has a new set of features. However, individual signs taken separately are widely known. So, it is known the use of the sleeve in devices for coating the inner surface of the pipeline (ed. St. USSR N 1404750, class F 16 L 58/10, 1984 and others). However, in the claimed solution, the sleeve, taken in a new connection with other features, allows the whole set to show a new property: to ensure reliable switching, to reduce friction losses. This gives reason to conclude that the claimed solution meets the criteria of the invention "significant differences".

 The drawing shows a device in cross section.

 The device comprises a housing made in the form of a sealed container 1, in which an elastic sleeve 2 is installed. One end of the sleeve is fixed in the container 1, and the other is wound on a drum 3, in which the switching elements are placed 4. The drum is fixed on an axis 5 connected to a coil spring 6. The housing is in communication with the working agent supply system 7.

 The device operates as follows.

 System 7 feeds the working agent into the container 1. Sleeve 2 moves downward, rotating the drum 3 and opening the switching elements 4. System 7 removes the working agent from the housing, spring 6 returns sleeve 2 to its original position, sleeve 2 presses and closes the switching elements 4.

 The use of the invention will allow, in comparison with the prototype, to obtain significant efforts on the switching elements. In places of final inclusions, hydraulic cylinder rods, mechanical levers and cams can be used, which will expand the operational capabilities of the device. Reliability, durability of the device increase, cost price decreases.
