摘要： A dosing device for dispensing very small quantities of liquid includes a variable displacement piston for varying the pressure within a chamber and valves located in inlet and outlet ducts communicating with the chamber. The valves preferably comprise a disc having a circular periphery and including passages therein which are radially spaced from the central portion of the disc. This central portion engages a valve seat to close off the corresponding duct and is preferably rigid to prevent permanent deformation of the disc. The peripheral edges of the disc are received in an annular groove and are free to move radially therein.

摘要： A liquid fuel pumping apparatus for supplying fuel to an internal combustion engine includes an injection pump which delivers fuel past a delivery valve. The delivery valve includes an axially movable valve element which is biased by a spring to the closed position, and is movable to the open position by fuel delivered by the injection pump. A restricted passage is provided in the valve element and which allows an additional flow of fuel between the injection pump and an outlet during the delivery stroke of the pump. The flow of fuel through the restricted passage is controlled by a valve member.

摘要： A fuel injection pump includes a fuel pump plunger which is movable to direct the fuel under pressure through a passage which is regulated by a delivery valve. The delivery valve includes a collar portion which, upon the return movement of the delivery valve, causes a sucking back or unloading action on the fuel in a direction toward the pump plunger chamber. The invention provides means for varying the fuel flow area in the return direction of movement of the delivery valve in accordance with the lift of the delivery valve during its operative opening movement. In one arrangement the delivery valve is constructed to close one or more escape ports during its downward return movement for slowing the return flow of the fuel to the plunger chamber and in another embodiment the delivery valve includes an end portion which provides a variable throttling action on a port communicating with the delivery valve passage and the pump plunger chamber.

摘要： A tide-powered unit for generating electrical power, comprising a relatively large-diameter cylinder and piston therein, disposed with their axes vertical, the piston being capable of a raising and lowering movement through the open top of the cylinder. The lower portion of the cylinder is attached to a base or anchorage located on the bottom of a large body of water the level of which is influenced by tides. The piston is operatively connected to a float whereby both will rise and fall as the tide comes in and goes out. The cylinder has inlet and outlet passages which are valved to permit ingress of water into the cylinder as the piston rises, and to provide for egress of water from the cylinder as the piston descends. The outlet, through which the water leaves the cylinder, goes to a reservoir located above the high tide mark whereby the rise and fall of the tide causes a pumping of tide water into the reservoir. When the reservoir fills, the water stored therein can be used to turn hydroelectric generators for generating electric power. A multiplicity of such power units is shown as being disposed side by side beneath a large platform whereby the latter is supported by the floats of the units and can carry buildings, equipment and other facilities. Where the supported platform is sufficiently large, it functions also as an air strip for the landing and take-off of aircraft. The platform imperceptably rises and falls with the tides whereby it is always at a given fixed level above the surface of the body of water. The large number of power units supporting the platform totalize to provide a large amount of ultimate hydroelectric power originating with the rise and fall of the tide. Automatically controlled water ballasts associated with the power units compensate for any unequal loading on the platform supported thereby.

摘要： The specification discloses an air pressure intensifier adapted to be supplied with air at a certain lower pressure and operable to increase the pressure of the air to a predetermined higher pressure. The device has reciprocating pistons driven by eccentrics and employs a cooling medium for cooling the pistons as the device operates. In one modification, the air pressure intensifier is connected in circuit with a source of air under pressure and only operates when the source drops to a certain lower level and turns off when the pressures reaches a predetermined amount.
