The system includes a gas inlet component, a compression component including a compressor; and an injection component having a compression component connection connected to one or more chambers of the compressor. By injecting a secondary high-pressure gas stream into the compressor through the injection component, the discharge flow rate of the compressor system may be increased above the flow rate capable based on the design of the compressor, without additional equipment or unduly increasing power consumption of the compressor system.



Steam Operated, Self Cycling, Diaphragm Water Pump

Thu, 13 Oct 2016 08:00:00 EDT

A diaphragm pump mechanism is powered by steam generated by an internal heater coil heating the pumped water, which moves the diaphragm and an attached piston to pump water through the pump. The heater coil is turned on-and-off using a switch that is timed to the movement of the pump. The water is pumped through a series of one-way rubber valves and reed valves to prevent a back flow of water. The pressure generated by the steam is released when a reed valve located on the diaphragm makes contact with a pin located on the body of the pump, opening the reed valve and allowing the steam to travel through and to condense. The piston and diaphragm are returned to the starting position when the steam pressure is released by a spring attached to the pump shaft. On the return stroke an accumulator refills the diaphragm chamber with water.



HIGH-PRESSURE CYLINDER ASSEMBLY FOR WATERJET INTENSIFIER PUMPS, AND RELATED METHODS

Thu, 13 Oct 2016 08:00:00 EDT

A high-pressure cylinder assembly for use with a waterjet intensifier pump includes a cylinder having a through bore and a radially inner surface extending along a length of the cylinder. A ceramic liner is provided in the through bore and contacts the radially inner surface of the cylinder. A first high-pressure seal is provided in the through bore of the cylinder and is constrained at a first end of the through bore. A second high-pressure seal is provided in the through bore and is constrained at a second end of the through bore. The first and second high-pressure seals are configured to maintain a sealed environment within the high-pressure cylinder assembly during operation of the waterjet intensifier pump.



DEVICE FOR DISPENSING SUBSTANCES

Thu, 13 Oct 2016 08:00:00 EDT

The device comprises a chamber (1) provided with an inlet (2) and an outlet (3); a piston (4) inside the chamber (1), the movement of which causes the exit of said substance; and a motor (5) with an output shaft (6) that drives the motion of said piston (4) when it receives a signal from a sensor; and transmission means that transmit the drive movement from the motor (5) to said piston (4); characterised in that said transmission means comprise: a worm gear (7) rotationally attached to the output shaft (6) of the motor (5); a first transmission element (8) connected to said piston (4); and a second transmission element (9) connected to said worm gear (7) and to said first transmission element (8). It enables small dimensions compared to conventional devices.



ELECTRIC LUBRICANT PUMP COMPRISING A CONNECTABLE DRIVE

Thu, 13 Oct 2016 08:00:00 EDT

A device for the supply of lubricant with a lubricant pump (101), which has a driveshaft (103), and a motor (107). The motor (107) is designed to drive the driveshaft (103). At least one clutch (109, 111, 113) serves to establish and/or interrupt a force flow between a shaft in the force flow of a transmission and the driveshaft (103).
