  • Patent number: 9969603
    Abstract: A filling element includes a common actuator that controls both a liquid valve and a gas valve. The actuator implements a two-stage control stroke. In a first operating state, both the liquid valve and the gas valve are closed. As a result of a first partial stroke in the second operating state, the gas valve opens but the liquid valve remains closed. Then, in a third operating state, as a result of a second partial stroke, the liquid valve is opens while the gas valve remains open.

  • Patent number: 4651897
    Abstract: A pump apparatus for viscous material adapted to be portable and includes a pair of upright supports defining a rigid framework mounted on a pair of wheels for movement along a support surface, such as a building floor. A platform extends perpendicularly outwardly from the framework and is adapted to support a container of material. A carriage is slideably mounted on a pair of guide rails secured to the framework, and a winch and cable assembly allows an operator to raise and lower the carriage. The carriage mounts a linearly arranged motor, drive shaft and pump, with the pump having a downwardly extending, disk-like follower plate oriented parallel to the platform. When a container is placed on the platform, the carriage may be lowered to insert the follower plate so that it bears against the materials. The motor drives the pump, and, as the material is removed from the container and dispensed through a hose, the weight of the carriage, pump and motor drives the follower plate into the container.

  • Patent number: 4602726
    Abstract: A dispensing device is disclosed which includes a tubular body having front and rear ends, the body having a central bore which narrows at the front thereof to form a tip. A piston is slidable in the bore, the bore space in the body forward of the piston defining a chamber. A supply bottle is removably mounted at the rear of the piston. The piston has a communicating passage between the bottle and the chamber. A first one-way valve means restricts flow in the communicating passage to occur only from the bottle toward the chamber. Also, a second one-way valve means restricts flow as between the chamber and the tip to occur only from the chamber toward the tip. The first one-way valve means includes a hollow valve body having one end which opens into the chamber and at least one port which communicates between the communicating passage and the inner region of the valve body.

  • Patent number: 4511065
    Abstract: A dispensing pump of the pressure accumulating type includes an assembly of a pump body and a separate piston member, the body including a closure cap for securing the assembly in fluid tight communication with the opening of a container of flowable product to be dispensed, a plunger/accumulator forming a variable volume pump chamber together with the piston and being reciprocable relative thereto, and a plunger head surrounding the plunger. The plunger has a vent seal for opening and closing a vent chamber defined around the piston. The closure cap is of a hard and durable material, while the separate piston is softer and more compliant which gives its lip seal good definition which avoids pump chamber leakage as it precisely conforms to the inner diameter of the plunger and to any irregularities thereof.

  • Patent number: 4260082
    Abstract: A manually operated, hand-held rechargeable liquid dispensing container device having a non-pressurized, either refillable or non-refillable receptacle or reservoir, is disclosed. The device comprises a relatively reciprocating piston and cylinder defining a pressurizable chamber therebetween which can be charged with liquid from the receptacle or reservoir in the container. The piston or cylinder is reciprocated relative to the other by a charging system connected to either one which compresses a resilient means such as a spring while simultaneously drawing liquid into the chamber through a check valve at the entrance of the liquid chamber. When the chamber is charged with liquid, hydraulic pressure is exerted upon the liquid by the now compressed spring. An improved charging system permits the hydraulic pressure application to be delayed until the check valve closes, insuring a full charge in the pressurizing chamber.

    Abstract: A manually operated sprayer for dispensing liquids from a container includes an improved, self-sealing outlet check valve having a resilient diaphragm convexed toward and in seating engagement with the dispensing orifice. The diaphragm is designed to flex out of engagement with the dispensing orifice when the pressure of the liquid in the pump chamber exceeds the engaging force of the diaphragm, thereby permitting the liquid in the pump chamber to flow out of the dispensing orifice in an atomized form.

  • Patent number: 4243159
    Abstract: A spring actuated pump device is mounted on a container for fluids, the device including a pump chamber into which fluid from the container can flow, the spring expanding and forcing a cylinder structure against the fluid in the chamber to pressurize it, in order that opening of a discharge valve will effect spraying of a desired quantity of fluid from the device, a suitable nut being threadedly connected to the cylinder structure to enable such structure to be shifted axially, in response to rotation of the nut relative to the container and cylinder structure, to compress the spring and store additional fluid pressure energy therein. A check valve permits ambient air to enter the container to prevent a vacuum condition from developing therein as fluid is withdrawn therefrom. Moreover, fluid is prevented from dribbling from the discharge valve of the device as the spring nears the end of its expansion range.

  • Patent number: 4207929
    Abstract: A material metering device and method for repetitively charging consistently accurate quantity charges of a lubricant retaining and wicking material to lubricant reservoirs of dynamoelectric machine bearings. A metering head is movably supported on a base for motion toward and away from a bearing and its support while both are held in alignment with the metering head. The metering head includes a dispensing chamber which may be sealingly coupled to the bearing support structure. The chamber receives lubricant retaining material from a source with excess material returning to the source. A valving arrangement interrupts the supply of material without substantially changing either the volume or pressure of the material in the dispensing chamber. An evacuation passage material flow path from the chamber to the bearing support structure or other workpiece is established and the material is extruded from the chamber.

  • Patent number: 4200204
    Abstract: A container for storing and dispensing a liquid product includes a pump operated by a reciprocable control member and associated with a pneumatic servo system. The actuation is achieved by supply of gas pressure, for example, from a reservoir of gas at a pressure of the order of 5 bars, and this is used to actuate the control member of the pump, for example a stepped piston incorporating a pressure multiplying effect. Much higher operating forces on the reciprocable control member can be achieved with this system than were possible by purely manual operation of the valve control member.
