    摘要： A pulsatile pump (P) the outlet of which is infinitely variable between a slow pulsatile flow and increased up to a sharply pulsed flow rate until the pulses run together and a smooth flow results, and which may be varied between wide output pressure and frequency limits. The pump is comprised of a pneumatic control circuit (90), at least two pneumatically isolated compression chambers (61, 63), and a novel inlet/outlet pump cartridge (50) and condition-responsive locking means (300). Operation of the pump is controlled by the use of novel tactile pneumatic response switches (110, 148, 168, 178). Each compression chamber is communicated with a supply of working fluid through the cartridge. Means are provided for varying the operation of the pneumatic circuit and hence the pump. A flow of pressurized fluid (72), such as air or nitrogen, is used as the operating media of the pneumatic circuit, although other fluids may be used. Means for monitoring and adjusting pump system parameters are also provided. The pump operates entirely through the use of pneumatic energy, avoiding the use of electricity.

    摘要： Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Verdichtung eines Gases oder eines Gasgemisches, bei dem ein erstes Gasgemisch (B) bereitgestellt wird, dessen Druckniveau niedriger ist das das Druckniveau eines zweiten Gases oder Gasgemisches (A), wobei die aus der Expansion des sich auf dem höheren Druckniveau befindenden zweiten Gases oder Gasgemisches (A) gewonnene Energie zum Verdichten des ersten Gases oder Gasgemisches (B) genutzt wird. Dabei erfolgt Verdichtung über wenigstens eine von dem zweiten Gas oder Gasgemisch (A) angetriebenen Antriebseinheit, wobei das erste Gas oder Gasgemisch (B) über eine fluidische Kopplung in einer oder mehreren Kompressionseinheiten verdichtet wird, indem die Übertragung der mechanischen Leistung durch Kopplung der wenigstens einen Antriebseinheit an die wenigstens eine Kompressionseinheit erfolgt.

    摘要： The ultra-high pressure booster or intensifier is a device consisting of two cylinders with two pistons, connected such that they operate simultaneously, which can be mounted in a multi-chamber containing simple pressure boosters nested (not mounted in series or in parallel) that can be used to increase the ultra-high pressure depending on the simple boosters being used. According to the invention, a flow of gas or liquid enters at pressure P1 and once filled at pressure P1, the flow enters into a simple pressure booster which is located inside chamber 1 and divides the flow into two parts: one part that is increased to pressure P2 and housed in another chamber 2 located inside chamber 1, using the energy released by the other part which is reduced to pressure P0 and released from the chamber 1. After several displacements when chamber 2 is at pressure P2, another simple pressure booster begins to operate, which is located inside the chamber 2 and divides the flow into a part that is increased to pressure P3 using energy from the other part which is reduced to pressure P1. After several displacements, chamber 3 is at pressure P3 and a new simple pressure booster and another chamber 4 are ready to continue increasing the pressure. In this way, with new boosters an ultra-high pressure Pn, as high as required, can be reached in chamber n. Each chamber can be formed by multiple walls or a series of sub-chambers, allowing greater resistance to be achieved. The invention can be used for ultra-high pressure sintering, preparing sterilized foodstuffs using ultra-high pressure or cutting materials, among others.

    摘要： The invention relates to the special configuration of a compression device of a refrigeration system and to its actuation method. The device consists of a pair of dual-action cylinders (8-9) connected together by means of the movable rod (11) thereof, such that the first cylinder (8) acts as an element for compressing coolant fluid, for which purpose the rod is moved through the second cylinder (9), being fed by a pressurised fluid which, by means of a series of branches and valves controlled using limit switches of the rod (11), allow the flow of coolant fluid in the first cylinder and the flow of pressurised fluid of the second cylinder at the outlet of both devices to be constant. Thus, a completely autonomous device that does not need electricity or any type of fuel is obtained.
