摘要： Apparatuses and methods overcoming the technical challenges in actuating valves of reciprocating compressors used in oil and gas industry are provided. A valve assembly includes an actuator, a shaft, a collar and a thrust bushing. The actuator is configured to generate a displacement. The shaft configured to receive a rotating motion caused by the displacement and to penetrate inside a compressor body of the reciprocating compressor. The collar is located close to a location where the shaft penetrates inside the compressor body. The thrust bushing is located between the collar and the compressor body. The rotating motion actuates a valve closing member of a valve inside the compressor body.

摘要： Reciprocating compressors 300 having a rotative valve 340 and related methods are provided. A reciprocating compressor 300 has (1) a compression chamber 310 configured to compress a fluid that has entered the compression chamber via an intake, and it is discharged from the compression chamber, after being compressed, via a discharge, (2) an actuator 350 configured to supply an angular displacement, and (3) a rotative valve 340 configured to receive the angular displacement and to determine whether the intake and the discharge are opened or closed depending on the angular displacement. The rotative valve 340 has a rotatable disk configured to rotate due to the angular displacement and having a first opening allowing a suction fluid flow to enter the compression chamber when the first opening overlaps the intake, and a second opening allowing a discharge fluid flow to exit from the compression chamber when the second opening overlaps the discharge.

摘要： The invention relates to a device for conserving power in a piston compressor, in particular for generating compressed air in a motor vehicle, having a piston (100) delimiting a compression chamber (500) for generating compressed air, which, originating from the ambient environment, arrives in the compression chamber (500) for compression by way of at least one suction connection (1) formed on a cylinder head cover (21) and an intake valve array arranged on a valve plate (2). For the purpose of conserving power, a pressure-dependently acting idling device is provided for the intake valve array having a dedicated suction lamella (4), which can be rotated by actuating means between a working position overlapping at least one suction opening (3) and an idling position unblocking, at least in part, the at least one suction opening (3). The invention is characterized in that the actuating means actuate the suction lamella (4) in a coordinated manner such that in the idling position, the section lamella (4) unblocks the at least one suction opening (3) in the valve plate (2), at least partially, while simultaneously blocking adjacent pressure valve cross-sections (5), at least partially, and locking the suction connection (1) at the cylinder head cover (21) by means of a slider (7) in order to form an increased harmful space in the area of the cylinder head (600).

摘要： A fluid pumping device comprising a pump housing (1; 101; 201; 301; 701; 901) containing a piston chamber (11; 101 '; 201 '; 310a, 301b; 701 '; 901 ' ) and a piston (2; 102; 202; 302, 302 '; 702; 902, 902 " ) moving back and forth inside the piston chamber, an inlet port (10i; 110i; 210i; 310i; 710i; 921) and an outlet port (10o; 110ο; 210o; 310o; 710o; 920) allowing a fluid to be sucked into the piston chamber during an instroke of the piston and expelled from the piston chamber during an outstroke. The device further comprises a valve - switching element (9; 109; 201; 309; 701; 909 ) movably mounted against a valve base member (7; 107; 207; 307; 707; 907), which comprises a piston chamber aperture (12p; 112p; 212p; 312p, 312p 1; 712p; 912p) connected to the piston chamber and an inlet aperture (12i; 112i; 212i;312i;712i;912i) and an outlet aperture (12o; 112o; 212o; 312o; 712o; 912o) connected respectively to the inlet and outlet ports of the fluid pumping device. The element comprises a groove (14; 114; 214; 314, 314 '; 714; 914) or other recess (514) moving against the valve base member such that, a first communication allows leakage between the inlet aperture and the piston chamber aperture so that fluid is sucked from the inlet port, through the groove or recess, into the piston chamber during part of the piston instroke, while a second communication allows leakage between the piston chamber aperture and the outlet aperture expelling fluid out of the piston chamber, through the groove or recess and the outlet port during part of the piston outstroke.
