Abstract: A hydraulic pump includes a work port configured to supply fluid to a hydraulic tool. A high-flow piston supplies fluid along a first flow path to the work port and plurality of high-pressure pistons supplies fluid along a second flow path to the work port. An unloading valve is positioned along the first flow path and actuates from an open state to a closed state when a pressure level of the fluid in the second flow path exceeds a first threshold pressure. A controller allows a user to select a mode of operation. The controller sets a second threshold pressure of the hydraulic pump based on the selected mode of operation, and the second threshold pressure corresponds to an end operation of the hydraulic tool.

Abstract: A hydraulic pump includes a work port, a high-flow piston, multiple high-pressure pistons, and an unloading valve. The work port couples to a fluid supply line of a hydraulic tool. The high-flow piston supplies fluid along a first flow path to the work port. The high-pressure pistons supply fluid along a second flow path to the work port. The unloading valve is fluidly coupled to the first flow path and the second flow path, and actuatable between an open state and a closed state. The unloading valve is configured to (i) permit fluid to flow from the high-flow piston to the work port in the open state, (ii) inhibit fluid from flowing from the high-flow piston to the work port in the closed state, and (iii) actuate from the open state to the closed state when a pressure of the fluid in the second flow path exceeds a threshold pressure.

Abstract: A method and an apparatus for cleaning a channel, especially a transmission and/or cooling channel, in any type of device, machine, installation, and/or tool, particularly in any type of heat exchanger and/or a molding core, cavity and/or insert is proposed, wherein a channel is cleaned through dynamic, bi-directional pulsation of cleaning medium inside the to-be-cleaned channel, the method being realized by a cleaning apparatus equipped with a diaphragm pump module, plugged either only in the feed side of the transmission line or in the feed side and in the return side, which, after connecting the diaphragm pump module to the external energy source and shutting off the flow control system from the reservoir and the feed pump, allows for putting cleaning medium into a state of two-way dynamic pulsating motion.

Abstract: The present invention relates to a reciprocating compressor able to operate with two separate pressure suction lines provided with a suction valves arrangement and, more particularly, to a suction valves arrangement whose suction valves have different thicknesses. In particular, at least one semi-commanded suction valve has a thickness greater than the thickness of at least one automatic suction valve. The present invention belongs to the field of fluid compressors.

Abstract: Embodiments are disclosed that relate to controlling a compressor. In one example, method of controlling a compressor comprises regulating a discharge capacity of the compressor via a control current supplied to a control device, holding the control current supplied to the control device at substantially zero amperes for a first duration, and stepping the control current from substantially zero amperes to a sustainable current that provides a sustainable level of a performance parameter of the compressor.

Abstract: A breast pump system includes a solenoid valve and a power source. The power source is arranged to supply electrical power to the solenoid valve so as enable the solenoid valve to move between first and second positions. The breast pump system also includes a controller configured to detect a change in inductance of the solenoid valve that is indicative of the solenoid valve moving from first to second position and a control action in which the vacuum pump is stopped.
