Abstract

A Stirling cycle machine has four two-piston modules with opposite cylinders with double-acting pistons connected to common rod and separating each cylinder into expansion chamber and compression chamber, at that expansion chamber of each module is connected by pipeline to compression chamber of neighboring module to circular circuit. Between the opposite cylinders a controlled double-acting hydraulic cylinder is placed coaxially, with piston installed at the middle of common rod, and between the cylinders and hydraulic cylinder a buffer zone is provided.

Description

working according to the direct Stirling cycle, produced by the 15 upper cylinders 5, 6, 7, 8 of each module are connected, received by a circular chain of cylinders with pipelines 19 with compression chambers 16 cores working according to the reverse cycle of Stirling upper cylinders 5, 6, 7, 8 in a circular chain, and ha; Namely: the expansion chamber of cylinder 5 is connected to - the impossibility of removing or feeding the mechanical compression chamber of cylinder 8, the expansion chamber of energy from the outside. cylinder 6 is connected to the compression chamber of the cylinder

The task of the useful model is to eliminate the specified 5, the cylinder expansion chamber 7 is connected to the cam by improving the design of the machine behind the cylinder compression swarm 6, the expansion chamber by the Stirling cycle with its multi-function cylinder 8 is connected to the cylinder compression chamber 7 . expansion 17 and compression 18 of the lower cylinders 9,

The problem is solved by the fact that in 10, 11, 12. Two Stirling cycle machines containing four heat exchangers and a regenerator (not shown in Fig.) are installed on pipelines 19. two-piston modules with oppositely located In modules 1, 2, 3, 4 between the upper 5, 6, 7, 8 and cylinders with double-acting pistons, connected by the lower 9, 10, 1, 12 cylinders coaxially located by a common rod and separating each cylinder is a double-acting hydraulic cylinder 20 with a piston 21, an expansion chamber and a compression chamber, and installed in the middle of the common rod 14, and the expansion chamber of each module is connected to the tru- between the cylinders and the hydraulic cylinder are formed by a buffer pipe with the compression chamber of the adjacent module zone 22 (Fig. 2). The cylinders and the hydraulic cylinder are connected in a circular chain, according to the useful model, between the corresponding seals 23 and 24. The hydraulic cylinders 20 are connected by oppositely located cylinders coaxially by communication pipelines 25 with the block, a controlled double-acting hydraulic cylinder is placed from the control (in Fig. not shown). by a piston installed in the middle of the general Depending on the mode of selection or supply of the current, and between the cylinders and the hydraulic cylinder, a machine according to the Stirling cycle is formed, which declares a buffer zone. sia, works like this.

Introduction to the design of the machine according to the cycle Example 1. As a cryogenic machine and a thermal one

Stirling, which is claimed, is controlled by a hydrocylin- pump. dra, transfers the mode of operation of the circular chain. They supply mechanical energy from any cylinder from the resonant to the controlled one, which allows the hydraulic pump (not shown in the figure) and thins to increase its power many times over and directs the exhaust under pressure to the block guide control - removes or feeds the mechanical energy of the rocylinders and then into the controlled hydraulic cylinders 20. from the outside. Thus, converting mechanical At the same time, the circular chain of cylinders 5, 6, 7, 8 energy from any source into thermal and cryo- begins to work according to the reverse Stirling gene cycle, and vice versa, thermal energy from any with a shift of the cycle by 90 " in the mode of the cryogenic machine to the mechanical one, reach the multifunction machine. As a result, thermal energy is pumped from the expansion chamber 15 to the compression chamber 16 and beyond

At the same time, in order to eliminate possible leaks with the help of the regenerator, a buffer zone is formed between the working gas of cylinders 5, 6, 7, 8 and the working gas of cylinders 5, 6, 7, 8 through the sealing of the cylinders. Osci- 9, 10, 11, 12, which also work in reverse, but in the working hydraulic cylinder, the liquid pressure is equal to the Stirling cycle, but in the heat pump mode. or above the maximum pressure of the working gas In the circular chain of cylinders 9, 10, 11, 12, the heat in the cylinders, the gas that has entered the buffer zone and the energy is pumped from the expansion chamber 17 through the cylinder seal and has an average pressure into the compression chamber 18 and through the recirculation heat exchanger will remain there because there is no opportunity for the consumer. From the end surfaces of the cylinders, liquefied gas ra gets into the liquid through the sealing of hydraulic cylinders 5, 6, 7, 8, which are condensers. At the same time, the gas at the moment of minimum pressure is collected in the Dewar vessels. of the cycle can, due to the sealing of the cylinder, turn- Example 2. As an engine and a heat pump. push back There are 15 cylinders 5, 6, 7, 8 in the expansion chamber

The essence of the claimed useful model is explained by providing thermal energy from any source, shown in the drawings, which show: on a, thermal energy is removed from the compression chamber 16

Fig. 1 is a schematic representation of the main nodes using regenerators. At the same time, the following machines, in Fig. 2 - a schematic representation of the two-part operation of the circular chain of cylinders 5, 6, 7, 8 of the spindle module. are set by hydraulic cylinders, which are simultaneously removed

Stirling cycle machine claimed power produced. From the regenerator, it contains four two-piston modules 1, 2, 3, 4, the total energy is taken by a heat pump in the upper 5, 6, 7, 8 and lower expansion chambers 17 and pumped into the comp chamber 9, 10, 11, 12 cylinders with pistons 13 of a double stroke 18 of a circular chain of cylinders 9, 10, 11, 12 and actions connected by a common rod 14. Pistons 13 are transferred from the heat exchanger to the consumer. With this double action, each cylinder is separated into a chamber. Excess heat, which needs to be disposed of from the expansion chamber 15 and the compression chamber 16 for the upper guns, is taken away by a heat pump and improves the operation of the cylinders and the expansion chamber 17 and the compression chamber of the engine itself, increasing it power 18 for the lower cylinders. Camera expansion and machine efficiency.
