Abstract: A plate or check valve, for diaphragm pumps, including a valve chamber in which at least one valve seat is provided that interacts with a valve plate that is elastically pretensioned via outer edge mountings such that a closing body of the valve plate can be moved from a closed position, in which it sealingly lies on the valve seat, into an open position against the elasticity of the valve plate. The outer edge mountings have webs and connecting brackets which are connected to the web ends facing away from the closing body. The outer edge mountings are disconnected from one another and only engage on the closing body, each of the outer edge mountings has at least two webs that are connected together via a connecting bracket, and each connecting bracket engages behind at least one paired holding base of the valve housing.

Abstract: A vacuum suspension system includes a foot cover having a heel portion and a pump system located in the heel portion. The pump system includes upper and lower sections arranged to move in an axial direction relative to one another and a pump mechanism operatively connected to and positioned between the upper and lower sections. When the heel portion is loaded in stance the pump mechanism moves from an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, to an expanded configuration in which the volume of the fluid chamber is increased.

Abstract: Thermochemical energy storage (TCES) for concentrating solar power (CSP) systems provides higher energy density than sensible energy storage systems. An ammonia-based TCES system dissociates endothermically into hydrogen and nitrogen. The stored energy is released when supercritical hydrogen and nitrogen react exothermically to synthesize ammonia. Prior ammonia synthesis systems are unable to produce temperatures consistent with modern power blocks requiring a working fluid, for example steam or carbon dioxide, to be heated to greater than 600° C., for example about 650° C. An ammonia synthesis system heats steam from, for example 350° C. to 650° C. under pressure of about 26 MPa. The hydrogen and nitrogen are preheated with a flow of supercritical fluid prior to the synthesis step to provide reaction rates sufficient to heat power block working fluid to the desired temperature.

Abstract: An electromagnetic vibrating diaphragm pump capable of increasing pump efficiency by increasing the vibration amplitude of the vibration of diaphragms even when the pressure inside a compression chamber is high. Diaphragms are fixed to both end portions of an oscillator having magnets. AC driven electromagnets are provided in a manner to face the magnets of the oscillator. A frame adhered to the outer peripheries of the diaphragms covers the electromagnet side, and pump casings cover the opposite sides. The pump casing includes a compression chamber adjacent to the diaphragm, a suction chamber connected to the compression chamber via a suction valve and an exhaust chamber connected to the compression chamber via an exhaust valve, the suction chamber or the exhaust chamber being connected to the frame via a continuous hole.

Abstract: A diaphragm pump includes a quick discharge valve unit that comprises a vessel including a supply passage, a check valve seat, a delivery passage and a discharge passage, and an elastic member configured to partition an internal space of the vessel into an input-side space connected to the supply passage and an output-side space connected to the delivery passage and the discharge passage. The elastic member includes a check valve body to prevent an inflow of air from the output-side space to the input-side space, and a discharge port valve body configured to close the discharge passage when air is supplied to the input-side space through the supply passage. The vessel includes a connecting path having a sectional area smaller than an area of a section of the supply passage, and configured to release pressurized air in the input-side space to an outside.
