A pressure booster for driving hydraulic tools has a gas or air pressure-driven pneumatic unit with a system line attaching to a compressed air inlet. An hydraulic unit is connected to the pneumatic unit. The hydraulic unit has a hydraulic connection to the fluid-tight connection of the hydraulic tool to the hydraulic unit. To provide a pressure booster which enables the use of electrically operated functional components independent of an external electrical connection, it is provided that a compressed air generator connected to the compressed air inlet is connected to an internal electrical consumer and/or a connection unit for connecting an external electrical consumer.

An inner cylinder inside an outer cylinder is disposed to be coaxial to an air pressure supply rod inside the inner cylinder. A first piston is disposed between the air pressure supply rod and the inner cylinder, a pneumatic chamber is disposed on a side of one surface (hydraulic surface) of the first piston in the inner cylinder, and a first hydraulic chamber is disposed on a side of the other surface. A second piston is disposed between the outer cylinder and the inner cylinder, and a second hydraulic chamber is disposed on a side of a surface of the second piston which is provided in the same direction as the hydraulic surface of the first piston in both of the cylinders. The inner cylinder is provided with a communication hole for transmitting a negative pressure along with movement of oil with which the first hydraulic chamber and the second hydraulic chamber are filled. In this configuration, it is possible to shorten an overall length of a fluid pressure cylinder.

A gas-over-oil actuator system for use with a valve in a natural gas pipeline. The system includes a gas-over-oil actuator and a wireless position monitor operatively coupled to the gas-over-oil actuator. The wireless position monitor includes an integral opened spool valve and is adapted to be communicatively coupled to a remote workstation via a wireless network and a wireless gateway. At least one switching relay is operatively coupled to the gas-over-oil actuator and the wireless position monitor. Upon receiving a wireless command from the remote workstation, the wireless position monitor drives a pressure signal from the opened center spool valve to the at least one switching relay to manage high pressure supply to the gas-over-oil actuator and move the valve to a desired position.

Systems, devices, and methods for utilizing hydrostatic and/or hydraulic pressure to generate energy and to separate water into hydrogen and oxygen are disclosed herein. A representative industrial system can comprise a storage tank containing fluid, a separator piston having a first separator compartment configured to be fluidically coupled to the storage tank and a second separator compartment, and a pressure intensifier. The pressure intensifier includes a first compartment, and a second compartment fluidically coupled to the second separator compartment. The second compartment of the pressure intensifier includes a pressure concentrator having a housing, a piston head member including arms, a plurality of cylinders each defined in part by the housing, and a drive piston head portion. Pressurized water may be depressurized by sending it through fine bore friction channels to produce water vapor and/or steam, which may then be injected into plasma reactors that separate water into hydrogen and oxygen. Some embodiments may involve injecting a catalyst into the plasma reactors with the water vapor and/or steam.

A hydraulic actuator with dual pneumatic operation, used in hydroelectric power plants, specifically in the field of hydropneumatic units generating hydraulic pressure for the operation of intake valves of hydroelectric power plants. The hydropneumatic actuator (1) comprises a hydropneumatic block (2) featuring two pneumatic pumps (4 and 4a) fixed to the base (32). This block accommodates the cup assembly (36), within which resides a cylinder (37) housing the plunger guide (38). The plunger guide (38) is attached to the shaft end (39), which is securely and firmly fastened to the cup end (36) using a guide nut (40). The hydraulic actuator (47) can be articulated by fitting the female eyelet (48) into the male eyelet (50), both of which being secured by the pin (51).
