A one-way valve device for air compressors including a disc-shaped element having a plurality of holes for flow of the air distributed along a portion having a circular crown extension, a sheet superposed on the disc-shaped element for occluding the holes, the sheet being susceptible to lifting due to the pushing action exerted by the air flowing through the holes, a spring opposing the lifting of the sheet, a containment and covering dome.

A fluid cylinder comprises a cylinder tube having a first tube end and a second tube end with respect to a tube axis of the cylinder tube, wherein the tube axis refers to the axis of the cylinder tube and the extension of the axis; an opening arranged at the first tube end for allowing fluid to enter into the cylinder tube; a piston; a sealing member arranged on the piston and adapted to provide a fluid-tight sealing between the piston and an inner wall of the cylinder tube; and a driving member adapted to drive the piston to perform a piston motion in the cylinder tube along the tube axis, wherein the cylinder tube, the opening, the piston, the sealing member, the inner wall and the driving member are adapted.

A check valve with improved response time comprises a valve member which has a central portion of a substantially convex shape and a guide portion that surrounds the central portion. The central portion has a central convex curvature extending towards the outlet port of the check valve, in the direction of the fluid flow. The guide portion has a weight to area ratio that is smaller than the weight to area ratio of the central portion. Such a check valve has an overall reduced weight of the valve member allowing a faster response time when the valve switches between its closed and open positions.

A screw-in valve connector includes a stationary connecting pipe with a pipe body and a drive portion. The pipe body includes an air intake portion, an air discharge portion, and a receiving hole. An elastic member is disposed in the receiving hole, and includes: a press end pressed against the air intake portion, and a force-receiving end. A stop includes: a lower end inserted in the force-receiving end, a stop end, an engaging portion between the lower and stop ends to stop against the force-receiving end, and an air passage penetrating the lower and stop ends. A positioning ring is sleeved onto the stop end to abut against the engaging portion, and includes a first threaded hole for threaded connection of a French valve. A rotary ring is pivotally connected to the air discharge portion, and includes a second threaded hole for threaded connection of an American valve.

A green community system centered around a transfer line compressed air energy storage system (TL-CAES). The TL-CAES system can supply compressed air to distant locations, and can be feed into companders to produce super-chilled air which can be used to improve the efficiency of natural gas generator sets. The generator sets can provide facilities with electricity and the super-chilled air can provide the facilities with heating, ventilation, and air-conditioning systems. The compressed air in the TL-CAES system is to be provided by a transportable compressed air storage system (T-CAES). Air compressors driven powered by green energy sources provide compressed air for the T-CAES system. The compressed air supply in conjunction with companders can further systems such as water purification and carbon dioxide extraction.

A valve assembly includes a seat plate having a top surface and a bottom surface, a plurality of first valve modules arranged in a first level relative to the seat plate such that a first seating face of each of the plurality of first valve modules is substantially co-planar with a first plane that is substantially parallel to at least one of the top surface and the bottom surface of the seat plate, and at least one second valve module arranged in a second level relative to the seat plate such that a second seating face of the at least one second valve module is co-planar with a second plane that is substantially parallel to the first plane, wherein the second plane is offset from the first plane by a first distance.

A valve comprising a base plate defining an inlet and outlet passageway. A cover plate is disposed on the base plate and defines a first and second channel. A pressure plate is disposed on the base plate and includes a first anchoring portion, a first sealing portion, and a first biasing portion connecting the first anchoring portion and the first sealing portion. Furthermore, a suction plate is disposed on the base plate and includes a second anchoring portion, a second sealing portion, and a second biasing portion connecting the second anchoring portion to the second sealing portion. The valve is movable between a first configuration, where the first sealing portion is distal to first channel and the second sealing portion is proximal to inlet passageway, and a second configuration, in which the first sealing portion is proximal to first channel, and second sealing portion is distal to inlet passageway.

A linear compressor is provided that may include a shell in which a discharge port may be provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a piston disposed to be reciprocated in an axial direction within the cylinder, a discharge valve disposed on or at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, a valve spring coupled to the discharge valve to provide a restoring force, and a stopper coupled to the valve spring to restrict deformation of the valve spring. The stopper may include a guide recessed in a direction in which the valve spring is deformed to reduce an impulse between the stopper and the valve spring.
