摘要： A reciprocating fluid pump may include a pump body, one or more subject fluid chambers within the pump body, one or more drive fluid chambers within the pump body, and a shuttle valve for shifting flow of pressurized drive fluid between two or more conduits. The shuttle valve includes a valve body and a spool disposed within the valve body and configured to move between a first position and a second position within the valve body. The shuttle valve also includes one or more magnets carried by the spool. The magnets are located and configured to impart a force on the spool responsive to a magnetic field such that the spool is magnetically biased away from an intermediate position between the first position and the second position.

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 a device for converting energy being stored in compressed air into mechanical work. Said device comprises the following structural parts: at least one compressed-air reservoir (1) for storing compressed air; several cylinder units (5a, 5b, 5c, 5d, 5e, 5f), whereby each unit comprises at least one pneumatic working room (10, 11) for bleeding the compressed air and at least one hydraulic working room (14, 15) for conveying the hydraulic medium, whereby the pneumatic working room (10, 11) and the hydraulic working room (14, 15) have a piston (13) respectively, whereby said pistons are coupled to each other; a hydraulic high-pressure circuit (22) being connected to the hydraulic working rooms (14, 15) of the cylinder units (5a, 5b, 5c, 5d, 5e, 5f) and being designed to transport a hydraulic medium which is exerted to high-pressure; a hydraulic motor being connected to the hydraulic high-pressure circuit and being driven by the hydraulic medium which is exerted to high-pressure. The aim of the invention is to achieve better efficiency. To this end, at least one reversing valve is provided which alternately connects the hydraulic working room (14, 15) of one cylinder unit to the hydraulic high-pressure circuit (22) or to the hydraulic working room (14, 15) of another cylinder unit (5a, 5b, 5c, 5d, 5e, 5f).
