    Abstract: An air operated double diaphragm pump comprising an air valve mechanism. The air valve mechanism may comprise a single valve system that replaces the two valve system found in conventional air operated double diaphragm pumps. The position of the valve may be determined by the diaphragm motion of the pump up to a stall position. A spring-loaded mechanical actuation may complete the valve action from the stall position to the final or end of stroke position of the pump.

    Abstract: In one embodiment a pneumatic motor is provided that includes an intake chamber in fluid communication with at least one intake channel. Each intake channel is further in fluid communication with a corresponding cylinder, which receives a piston that cycles upwardly and downwardly to rotate a motor axle. A member is placed in each intake channel to seal the corresponding cylinder from each intake channel when compressed fluid in the intake channel has a higher pressure then pressure in the corresponding cylinder. Each piston includes an actuator extending downwardly from the piston and having a profile that, during a portion of the upward cycle of the piston, causes the actuator to push the member back into each intake channel to allow compressed fluid into each of the corresponding cylinders. Each piston includes a section that has a diameter that creates a seal against the corresponding cylinder during the upward cycle of the piston. Compressed fluid that enters the corresponding cylinder during the upward cycle will push the piston upwardly. Each section further includes exhaust grooves defined thereon such during the downward cycle of the piston the seal is broken allowing compressed fluid in the cylinder to bypass the piston and escape through a vent above each cylinder. This causes the compressed fluid in the intake channel to push the member to re-seal the cylinder. The upward movement of the piston further generates inertia that moves the piston downward to continue the cycle.

    Abstract: An apparatus for intermittently atomizing a fluid with the assistance of a gas or a mixture of gases. The apparatus includes a cylinder having a cylinder head with a valve seat and at least one flow passage, a piston driven within the cylinder by a rotating crankshaft, an injection valve having a valve head and a spring element urging the valve head into engagement with the valve seat to close the flow passage. The injection valve generally includes an actuating surface that cooperates with the piston to mechanically open the valve when the piston reaches the end of its compression stroke. As a result, the present invention delays the start of valve opening until the piston maximizes the atomizing pressure within the cylinder thereby advantageously maintaining small fluid drop sizes. Additionally, flow passages formed within or proximate to the valve head provide a corridor through which the cloud of drops enter the combustion chamber. Altering the size, shape and orientation of the flow passages allows the shape and direction of the cloud of drops protruding from the flow passage to be varied for different applications. Finally, the injection valve preferably includes mechanical guidance at both its axial ends to reduce edge stresses and increase the durability of the valve.

    Abstract: A direct action fluid motor and injection pump is disclosed which injects small quantities of a second fluid into a primary fluid stream. A housing has an inlet and an outlet connected to a primary fluid conduit. The housing contains a stepped piston which reciprocates in response to the fluid pressure applied alternately to the closed small and large face of the piston. A valve set alternately closes one and opens the other of the faces. A valve positioner carried with the piston is held in alternate stable positions by cooperating springs on the valve positioner and a post in the piston. Stop members are located above and below the piston travel, each associated with an actuating spring. The valve positioner is preshifted at the end of the stroke, using the full force of the piston, by stop members to move the valve positioner and valve set to an intermediate unstable position. When the closed valves on the closed face are unseated a small distance, a relatively weak actuating spring can then fully shift the valve positioner and valves to change the direction of reciprocation. The injection pump has a pump casing connected in sealed contact with the motor housing and has an outlet leading to the secondary fluid. A reciprocating pump mechanism connected to the piston has a selectively adjustable sliding valve member which closes the pump chamber at a plurality of predetermined positions of the pump mechanism. The pump mechanism displaces fluid from the pump chamber without sliding seals. Displaced secondary fluid travels under pressure through a control passage to mix with primary fluid at the outlet of the pump housing. The pump casing is quickly and easily removable for access to the pump mechanism to rapidly adjust the ratio of secondary fluid. The pump self primes automatically with primary fluid, if needed, at the bottom of its stroke.

    Abstract: A uniflow engine has a plurality of cylinders disposed symmetrically around a common crankshaft connected to pistons reciprocating in the cylinders. In response to the availability of a working fluid vapor at a predetermined condition, such as a high pressure or temperature, incoming vapor is supplied to those cylinders in which the respective pistons are in their working strokes to thereby initiate rotation of the crankshaft in a predetermined direction regardless of the position in which the crankshaft has stopped last. Once rotation is initiated and a predetermined mode change speed attained in a "start-up mode" by engine operation from start, vapor inlet valves are controlled to change engine operation over to a "running mode". In the "start-up mode" incoming vapor is admitted over a substantial portion of the piston working stroke, whereas in the "running mode" vapor inflow is terminated relatively early in the working stroke so that a vapor change does work in expanding against the piston. A relief valve is provided in the head portion of each piston and is actuated by inertia forces to facilitate evacuation of exhausted working fluid vapor from the corresponding cylinder.

    Abstract: A fluid flow machine wherein a reciprocating piston type pump for a flowable material which must be subjected to a pronounced pressurizing action is operated by a double-acting pneumatic motor which is disposed at a level above and is spaced apart from the pump. The unit which regulates the admission of compressed air into and the evacuation of spent air from the motor is installed between the motor and the pump at a level immediately above a chamber for a supply of liquid medium serving to lubricate and clean the piston rod which transmits motion from the piston of the motor to the pump piston. A common cylindrical envelope which is permeable to air surrounds the motor and the regulating unit and defines a large expansion chamber for spent air to thus reduce noise when the machine is in use. The regulating unit need not extend radially beyond the motor and/or pump housing, and this unit occupies space which is invariably provided between the chamber and the motor so that the placing of the regulating unit into such space does not contribute to the bulk of the machine.
