A valve for controlling fluid flow. The valve include a support element providing a flow path, at least a portion of the flow path extending along an axis of flow through the valve. A flexible element is compressible against the support element to interrupt the flow path and restrict fluid flow through the valve. An actuating element is movable along the axis of flow to engage and deform the flexible element against the support element.

The present invention relates to a fluid connector, comprising a shaft having at least one solid shaft element and a plurality of connector surfaces, wherein the plurality of connector surfaces includes a surface with a plurality of threads and a plurality of grooves.

A dual outlet valve is provided that is capable of obtaining a closed state for both outlet ports, a low flow for either operating port either individually or combined, or a high flow operation mode for either outlet port individually or combined such that at least seven different operating conditions can be obtained.

The piston of a fluid motor divides the cylinder into two variable volumes into which and from which fluid may be selectively introduced and exhausted via ports through the cylinder to relatively move the piston and the cylinder. The piston is modified to define two fixed-volume chambers that respectively communicate with the variable volumes via restrictive orifices. In selected relative piston-cylinder positions, the chambers communicate with the ports to restrict fluid flow into and out of th...

A fluid machine according to the present invention has an expansion-and-compressor device selectively operating as an expansion device for collecting waste heat from an internal combustion engine and converting the collected heat energy into mechanical rotational force, and as a compressor device for compressing refrigerant for a refrigerating cycle for air conditioner. The fluid machine further comprises an electric rotating device selectively operating as an electric power generator and as an ...

A fluid dispenser comprising: two sheets (1, 1'), at least one of which is deformable, the two sheets forming a fluid reservoir (15) between them, said at least one deformable sheet defining a deformable actuating wall so as to reduce the volume of the reservoir, the reservoir (15) advantageously being provided with resilient means (4) urging the reservoir towards its maximum volume; and a dispensing piece (2) fixed in leaktight manner between the two sheets (1, 1') and defining a dispensing ori...

A hydrant comprising a housing forming a reservoir; and a piston configured to force residual fluid out of the reservoir to an outlet and to allow supply fluid to flow from an inlet through the piston to the outlet when the piston is actuated in the housing to a first position, and when the piston is actuated in the housing to a second position, to restrict flow of the supply fluid to the outlet and to allow at least a portion of the supply fluid that has flowed from the inlet to flow into the r...

A substantially clog-resistant self-supporting fluid filter 100 for attachment to an open end of flow tube 118. Filter 100 comprises a substantially cylindrically shaped grid or fluid intake portion 102 having first end 112 and a second end 116. Fluid intake portion 102 comprises a plurality of substantially parallel longitudinal ribs 106 affixed to a plurality of substantially parallel circular ribs 108 at an angle to longitudinal ribs 106 thereby allowing a fluid to flow therebetween while pre...

A fluid machinery such as helical compressor includes a sliding mechanism comprising one side member composed, in combination, of a metallic base member having a sliding surface and a lubrication film formed on the sliding surface in a close contact thereto, and a counterpart side member containing fluorocarbon resin in an amount of at least 50 wt. %. The lubrication film includes a solid lubricant having a self-lubrication property and a binder of resin material.

A fluid coupling comprising a pump having an annular pump shell with an annular core ring mounted on a pump hub and a plurality of impellers radially arranged in the pump shell, and a turbine arranged facing the pump and having an annular turbine shell with an annular core ring mounted on a turbine hub that can rotate relative to the pump hub and a plurality of runners radially arranged in the turbine shell, wherein the turbine shell is so constituted to slide on the turbine hub in the axial dir...
