Abstract: A device operable from a primary supply of water under pressure, such as a domestic water supply, to be used with irrigation and sprinkler systems, that modulates the flow of water supplied to different outlets, herein called supply heads, periodically from a minimum to a maximum flow rate and also provides a means by which liquid fertilizer and insecticides and the like can be dispensed and applied evenly and safely over a surface without human contact. As contemplated by the invention, supply pressure from a primary water supply is transformed into rotational motion which in turn, operates a rotary valve creating a water effluent therefrom that varies in its flow rate in accordance with the cyclical periodic operation of said rotary valve. This water effluent is delivered to the supply heads of the irrigation or sprinkler system. The rotary valve may be disabled so as to permit nearly straight-through passage of the supply water. The device of the invention may be installed in an existing irrigation or sprinkler system, preferably downstream following a conventional anti-siphon valve so as to prevent any possible chemical migration and contamination into the primary water supply. Thus, using the advantages of the invention, a more even distribution of water over a surface may be accomplished thereby reducing water consumption due to saturation watering from the attendant wasteful run-off. The device may be used with conventional automatic timers.

Abstract: Apparatus for admitting a cleaning agent into the vacuum line of an animal milking installation has a reservoir the lower portion of which communicates with an intake portion of the vacuum line, a metering device having a vessel which is installed in the upper portion of the reservoir, valved conduits which connect the vacuum line with a source of water and with the upper part of the vessel, a source of cleaning agent which is connected to and admits into the vessel cleaning agent when the vessel is connected to the vacuum line, a buoyant valve element which floats on the supply of cleaning agent in the vessel and seals the vessel from the vacuum line when the supply of cleaning agent in the vessel rises to a predetermined level, and a valve which allows the supply of cleaning agent to flow into the reservoir when the pressure differential between the interior of the vessel and the reservoir decreases to a predetermined value subsequent to sealing of the vacuum line from the interior of the vessel. The pressure differential decreases owing to the provision of a flow restricting orifice which connects the interior of the vessel with the surrounding atmosphere or with the interior of the reservoir.

Abstract: A flush valve for releasing a predetermined volume of liquid upon actuation thereof includes a valve housing having an inlet, an outlet, a valve seating surface circumventing the inlet and a piston housing portion adjacent to the outlet. The piston is movable between an opened and a closed position and has one end sealable with the valve seating surface when the piston is in the closed position to block the flow of liquid from the inlet to the outlet. Upon actuation of the valve, the piston is unsealed from the seating surface to permit liquid to flow from the inlet to the outlet. The other end of the piston is sealed to the piston housing portion and a control chamber is provided having an expanding portion between the piston and the piston housing portion. Restricted flow of liquid from the control chamber to the outlet is permitted. Means are provided for selectively conducting the pressurized liquid from the inlet to the control chamber to create a resultant force urging the piston to the open position upon actuation of the valve and for disconnecting the pressurized liquid from the inlet to the control chamber when the piston reaches the open position. Means are provided for adjusting the predetermined volume of the liquid released by the flush valve upon actuation thereof and for limiting the volume of liquid released by the flush valve to the predetermined amount.

Abstract: The invention relates to a volumetric valve which supplies a displayed liquid volume. This valve has a turbine which is rotated by the liquid and which drives a disk via a gear train. The disk rotates a spiral spring and a ring provided with a slot. A sliding push rod controls the opening of the valve flap and carries a lug which penetrates the slot. A knob makes it possible to vary the angular clearance between the slot and the lug, which determines the displayed volume.

Abstract: A trigger valve which closes a main valve after a predetermined volume of fluid passes therethrough is equipped with a conversion mechanism arranged in the flow path of the fluid and functioning to translate the amount of fluid flowing through into a proportional amount of motion. A cam mechanism is turned by the conversion mechanism. The trigger valve closes the valve disk automatically due to the function of the cam mechanism when the fluid has flowed in a pre-determined quantity. Examples demonstrate the ability to control the valve means to increase or decrease a pre-determined standard flow of fluid at will by manipulations of a control mechanism.

Abstract: Apparatus for selectively venting a pressure-sensitive fluid system. Fluid pressure of the system is directed through a first conduit into a chamber having an expandable wall portion and through a second conduit which terminates in an opening adjacent and facing the external surface of the expandable wall. Small system pressure fluctuations are vented through the opening of the second conduit and large pressure changes cause the expandable wall portion to extend into sealing contact with the termination of the second conduit, thereby closing the vent opening. System fluid pressure may also be directed through a third conduit into a second expandable wall fluid chamber and the expansion of that wall utilized to actuate an electrical switch.
