摘要： Volume body masses with lower density than the gas in which the above are located, rise as a result of the reduced gravitational effect of the body relative to the gas. The possibility thus arises of using the mechanical lift for partial load reduction in a power process, whereby, in reduction chambers (45) within a cylinder (24), working forces, load on the reduction surfaces (35) and also on the baseplate are exerted and internal gas pressure surface forces in the reduction pressure chambers (45), on the reduction surfaces (35), counteract the basic pressure force, acting, on one side, from the side of base sliding plate (36) towards the base pressure chamber (44). On the opposing faces of said volumes the gas pressure surface forces of the gas pressure media lead to a low pressure in the chamber (46) with a mechanical lift, to give a directional gas pressure force in a machine system, or to constantly maintain an accelerated movement for the machine system.

摘要： The invention relates to a machine for dispensing beverages from a pod (4) comprising at least two cavities (8a, 8b), each cavity containing a volume (VI1, VI2) of ingredients forming part of the composition of the beverage. The machine comprises an air injection device (19) configured to supply at least two volumes of air (Va1, Va2) in a synchronised manner, said volumes of air being adapted respectively to the volumes of ingredients in each of the cavities. The air injection device allows the ingredients to be discharged steadily from the cavities, so that they can be transferred gradually into a mixing chamber in the pod (4) throughout the preparation of the beverage, thereby allowing the ingredients to be diluted homogeneously with water in the mixing chamber, and said homogeneous mixture being released gradually into a container. Since the volumes of air supplied are adapted to the volumes of ingredients in the cavities all of the ingredients are discharged.

摘要： Disclosed are a fold-back coaxial gas booster pump and a gas pressure creating method, belonging to the field of gas pressure creation. The fold-back coaxial gas booster pump comprises a primary gas cylinder, a primary piston, a secondary gas cylinder serving as a primary piston connecting rod, a pressure rod, a gas pump cover, a secondary piston and a piston connecting rod, wherein the primary gas cylinder, the secondary gas cylinder and the piston connecting rod are coaxially installed, and the rear end of the piston connecting rod penetrates through a first follow-up one-way valve installed in the primary piston and is fixed on the bottom wall of the primary gas cylinder, so that the two pistons move in opposite directions to boost the pressure. The fold-back coaxial gas booster pump is composed of a two-stage compression gas pump, and can realize two stages of compression during one movement, so that the gas compression reaches a higher pressure range, the gas compression efficiency is improved, the power required for compressing gas is reduced, and the fold-back design enables the product to be miniaturized. The fold-back coaxial gas booster pump is pressure creating equipment which is light in weight, convenient to carry and high in pressure, and is suitable for field instrument calibration.

摘要： A rapidly modulated hydraulic supply is disclosed. The rapidly modulated hydraulic supply can include a chamber for receiving fluid. The rapidly modulated hydraulic supply can also include a displacement member operable to displace the fluid from the chamber. In addition, the rapidly modulated hydraulic supply can include a flow modulation system operable to vary the flow rate of the fluid output from the chamber. A first flow rate corresponds to a first output pressure, and is different from a second flow rate corresponding to a second output pressure for a like movement of the displacement member.

摘要： A pumping assembly having a high-pressure pumping stage and an integrated transfer pumping stage. The pumping assembly comprises a cam (104;204) arranged for eccentric rotation about a drive shaft axis (A), a cam rider (106;206), a cam follower (112;212), the cam follower (112;212) having reciprocal movement parallel to a cam follower axis (Q) that is perpendicular to the drive shaft axis (A), a high-pressure pumping head having a high-pressure pumping chamber, and a pumping element driven by the cam follower (112;212). The pumping assembly further comprises a first chamber (150a;250a), inlet means (174;274) for allowing fluid flow into the first chamber (150a;250a), and outlet means (150b,163,166,166a;250b,263,266,266a) for receiving fluid from the first chamber (150a;250a) and for delivering fluid to the high-pressure pumping head. Rotation of the cam (104;204) about the driveshaft axis (A) causes an increase in volume of the first chamber (150a;250a) during a first part of the pumping cycle and a decrease in volume of the first chamber (150a;250a) during a second part of the pumping cycle, so as to effect a transfer pumping of fluid from the inlet means (174;274) to the outlet means (150b,163,166,166a;250b,263,266,266a) for delivery to the high-pressure pumping head.

摘要： The compressor includes a cylindrical housing (1), in the bore of which moves a piston (3) whose periphery is adjusted with little play in the cylinder (1). The end (5) of the piston (3) includes a gas inlet (6) and supports two spherical joints (7) as well as connecting rods (8, 8') which are symmetrical in relation to the axis of the piston (3). The connecting rods (8, 8') pass with play through a transverse wall (11) of the housing (1) and are driven by a mechanical member (13), which includes a mobile component (14) having a rectilinear reciprocating movement, and by a compensator (15). The connecting rods (8, 8') are connected to the compensator (15) by means of ball joints (16, 16') and the compensator (15) is connected by a ball sorbet joint (17) to the mobile component (14). Application: in the manufacture of piston-cylinder machines, in which the piston is driven in a relative reciprocating movement without radial load transmission.
