    Abstract: The present invention refers to a system for actuation in an ad mission valve (5) of a gas compressor (1) comprising at least: one set formed by a cylinder (2) and a piston (3); one electric motor (4), operatively associated with said set, capable of providing an axial movement of the piston (3) to compress the gas inside the cylinder (2), the admission valve (5) being configured to allow the input of gas inside the cylinder (2) upon the axial movement of the piston (3) in a first axial direction; and a discharge valve (6) con¬ figured to allow the output of gas from inside the cylinder (2) upon the axial movement of the piston (3) in a second axial direction opposite to the first axial direction. The system comprises at least one actuator element (7), operatively associated with the admission valve (5), capable of keeping the admission valve (5) open when the electric motor (4) stops and starts-up. The actuator element (7) is also capable of allowing opening and closing of the admission valve (5) upon the regime of work of the electric motor (4). The present invention also refers to a gas compressor (1 ) which comprises the above-mentioned system. The present invention also refers to a refrigeration equipment which comprises the above-mentioned gas compressor (1 ).

    Abstract: A valve stop retainer device (220) that is adapted to interface with a cross-bore fluid communication chamber (262) of a reciprocating pump (250) includes a spring retainer plate (221) and a plurality of retainer lobes (223) extending substantially away from a first side of the spring retainer plate (221). Each of the plurality of retainer lobes (223) includes an upper portion (223u) having an outer surface (223s). A shape of each of the outer surfaces (223s) and a shape of an inside surface (261) of the cross-bore fluid communication chamber (262) interfacing with the valve stop retainer device (220) substantially conform to a shape of at least a portion of a surface of revolution. The valve stop retainer device (220) is adapted to be retained inside of the cross-bore fluid communication chamber (262) by the shape of the inside surface (261).
