Abstract: A connecting structure, an exhaust silencer, a silencer and a compressor are provided. The connecting structure has a connecting housing and an exhaust pipe assembly. The connecting housing has a silencing chamber and a sealing portion. One end of the exhaust pipe assembly passes through the sealing portion and extends into the silencing chamber. Another end of the exhaust pipe assembly is arranged outside the connecting housing. Thus, the silencing chamber is in communication with an outside space of the connecting housing through the exhaust pipe assembly.

Abstract: A process for manufacturing a device and the device for damping pressure pulsations for a compressor of a gaseous fluid, in particular a refrigerant, in a refrigerant circuit of a motor vehicle air-conditioning system. The device exhibits a housing that encompasses a chamber and features at least two outlet openings. Here, the housing is constructed between tubular connecting lines, whose ends are aligned with one another. An insert element for reducing the cross-sectional area of the pass-through opening is arranged inside at least one of the pass-through openings.

Abstract: A portable air pump includes a pumping assembly and an inflating assembly. The pumping assembly includes an inner cylinder and an outer cylinder. The inner cylinder is provided with a first end and a second end, and the outer cylinder is sleeved onto an outer periphery of the inner cylinder from the first end. The inflating assembly includes a sliding member, an inflating tube, and a pivoting member. The sliding member is disposed in the inner cylinder. The inflating tube has a proximal end connected with the pivoting member. The pivoting member is pivotally mounted on the sliding member to be rotatable between an axial position and a radial position. When the pivoting member is in the axial position, the sliding member is movable between a retracted position and an extended position.

Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

Abstract: The device (40) performs the decompression of a first gas container (12) by extracting gas present in this first container, compressing the extracted gas and injecting the compressed gas into a second gas container (13).
The device comprises: a source of compressed air (14); a pneumatic booster (30) equipped with an expansion chamber (17) and a compression chamber (23); a first pipe (31), for air, between the compressed air outlet of the source of compressed air and an inlet (18) of the expansion chamber; a second pipe (32), for air, connected to an outlet (19) of the expansion chamber; a third pipe (33), for gas, between the first container and an inlet (15) of the compression chamber; and a fourth pipe (34), for compressed gas, between an outlet (16) of the compression chamber and the second gas container.
