  • Patent number: 8226380
    Abstract: The invention relates to a chamber, in particular a pump chamber, comprising a plate-shaped first half (10) and a plate-shaped second half (12). The first and second halves are connected to one another by a closed connecting seam (20) in a surface-to-surface relation, and at least one half has at least one aperture (14) lying within the connecting seam. Furthermore, at least the second half is thermally deformed within the closed connecting seam in such a manner that it is formed to bulge relative to the connecting surface with the first half such that a hollow space (30) is formed between the first and second halves. In a second aspect, the invention relates to a pump having a configuration as described above. In a third aspect, the invention relates to a method for producing a chamber as described above.

  • Patent number: 8157538
    Abstract: An apparatus is provided and may include a compression mechanism, a valve plate associated with the compression mechanism and having at least one port in fluid communication with the compression mechanism, and a manifold disposed adjacent to the valve plate. A cylinder may be formed in the manifold and a piston may be disposed within the manifold and may be movable relative to the manifold between a first position separated from the valve plate and a second position engaging the valve plate. A valve element may be disposed within the piston and may be movable relative to the piston and the manifold. The valve element may be movable between an open position spaced apart from the valve plate and permitting flow through the port and into the compression mechanism and a closed position engaging the valve plate and restricting flow through the port and into the compression mechanism.

  • Publication number: 20110206545
    Abstract: The pump includes a housing containing a hollow elongated part, a piston arranged to move back and forth inside an elongated part, an inlet port and an outlet port arranged so that a fluid can be sucked through the inlet port into a chamber during an instroke of the piston and expelled through the outlet port during an outstroke. A linearly and/or angularly actuable valve system has a valve holder mounted on the pump housing which includes at least one through-hole extending from the piston chamber to the housing outer surface. The valve holder contains an inlet and/or outlet to alternately connect the inlet and outlet ports of the volumetric pump.

  • Publication number: 20090180906
    Abstract: An economically desirable hydraulic pump which can reduce manufacturing costs or running costs significantly. The hydraulic pump comprises a waterway through which water is fed into a pump outer wall body. A moving pressing member compresses a lower reservoir to move downward as water is fed, and to move upward due to buoyancy as the water is discharged after being fed. A pumping pipe transports the water that is fed due to the downward movement of the moving pressing member, and a discharge pipe discharges water in the moving pressure applying member at the low position. The moving pressing member comprises an open/close valve which controls whether to feed the water into its internal space, and a water passage valve which controls whether to feed water from the waterway to the lower reservoir. The water passage valve is allowed to open as the moving pressing member surfaces, and is allowed to close as the moving pressing member ceases to surface.

  • Patent number: 4716720
    Abstract: A combustion engine has a combustion chamber separated from the compression and expansion chamber(s). Passages are provided between the combustion chamber and the compression chamber(s) and the combustion chamber and the expansion chamber(s) with respective valves in the passages and inlet and exhaust valves provided in the combustion and expansion chamber. The combustion chamber maintains the combustion after passing fuel into the compressed air received from the compression chamber. The valves and piston heads are formed to prevent dead space in the cylinders in order to obtain a good efficiency by full discharge of the compressed air into the combustion chamber. Fuel cleaning means like, for example, a rotary separator and pure gas collector are provided in the combustion chamber to separate unclean fuel particles, as, for example, ash or sand in coal, from the burned gases and collect the unclean particles in separated collection spaces.

  • Patent number: 4370103
    Abstract: A piston pump mechanism for use in positive pressure and vacuum pumping systems for pumping various gases such as air, freon, natural gas, etc. The pump mechanism incorporates an inlet and discharge valve system that substantially eliminates any unpurged or unswept volume of gas within a pump cylinder during each reciprocating stroke of the pump piston. The pump mechanism also incorporates a control spool that floats within a pump head and has a sealed flexible interconnection with the discharge valve that allows the discharge valve to seek optimum seating engagement about the entire periphery of the cylinder. The valve control spool may be pressure balanced or controllably unbalanced, as desired, for influence of the discharge valve. The spool also provides for inlet of gas to an inlet valve that may be incorporated into the discharge valve.

  • Patent number: 4084731
    Abstract: An atomizing pump assembly for use with a variety of types of containers is disclosed in which a housing is formed with both an outlet port and an internal fluid chamber that communicates via a passageway with the outlet port. Tubular means provides communication between the fluid chamber in the housing and a reservoir of the material that is to be dispensed by the pump. A flexible frustroconical skirt or diaphragm having a valved opening therethrough is operatively located intermediate the tubular means and both the fluid chamber and the outlet port, with an integral upper portion of the diaphragm initially obstructing the outlet port. When an actuating cap is depressed, material within the fluid chamber is compressed until a minimum predetermined chamber pressure is achieved, whereby under pressure the skirt or diaphragm is flexed from its normal position to a discharge position.
