A device for conveying viscous material out of a barrel-like container which has a container base and a container shell which extends upward from the container base, having a follower plate for closing off the container. The follower plate having a material outlet opening and a ventilation opening. There is a pump for conveying the viscous material through the material outlet opening, and a ventilation device for introducing compressed air through the ventilation opening, and a lowering device for lowering the follower plate in the container. A discharge valve is provided which, in a first switching position, blocks a line which leads out of the first pressure chamber, and which, in a second switching position, opens the line for the purposes of discharging pressure medium out of the first pressure chamber.

A hydro-cleaning manual system, in particular apt to the cleaning of a WC, comprising a liquid jet device and a supporting/reservoir device.

A dispensing system for dispensing an associated substantially viscous product includes a dispensing system housing and a first container. The first container is disposed within the dispensing system housing and has an elastically deformable wall defining a changeable volume for containing the associated product. The elastically deformable wall is expandable between an unexpanded state and an expanded state. The first container includes an outlet through which the associated product is expelled. Potential energy stored in the deformable wall in the expanded state is operable to expel the associated product from the first container through the outlet. The dispensing system includes a selectively engage-able valve operatively fluidly connected to the outlet for controlling the expulsion of a predetermined amount of the associated product from the outlet. An actuator is operatively coupled to the valve to selectively engage the valve.

Techniques herein include a bladder-based dispense system using an elongate bladder configured to selectively expand and contract to assist with dispense actions. This dispense system compensates for filter-lag, which often accompanies fluid filtering for microfabrication. This dispense system also provides a high-purity and high precision dispense unit. A modular hydraulic unit houses the elongate bladder and hydraulic fluid in contact with an exterior surface of the bladder. When pressurized process fluid is in the elongate bladder, hydraulic controls can selectively reduce pressure on the bladder to cause expansion, and then selectively increase hydraulic pressure to assist with a dispense action.

The combination of a container of a first volume and a fluid containment and dispensing apparatus includes a flexible bag having an inner wall, an outer wall and a collar. The collar comprises a plurality of components, including a collar body, a flange that is attached to the bag, and a top plate having a first aperture therein configured to for connection to a first fluid carrying conduit, the fluid carrying conduit providing for egress of fluid from the bag. The container comprises walls the walls having inner and outer surfaces, and the collar body extends from a wall of the container. The container provides at least one second aperture providing for ingress and egress of fluid to and from a space situated between the outer surface of the bag and the inner surface of the container and the apparatus further comprises fastening means to fasten the collar components together.

An orientation independent delivery device including a replaceable cartridge that may be installed on a foundation. A cartridge includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

Disclosed is a supply device for supplying a consumer with a viscous medium, in particular a lubricant supply device, including at least a reservoir for the viscous medium including a follower piston which includes a ring seal at its circumferential edges and is supported on the viscous medium and which separates the reservoir into a space supplied with a viscous medium and an air space, and a feed pump for feeding the viscous medium from the reservoir to a medium outlet, such that further in the reservoir at least one opening is provided which serves to receive a ventilation apparatus via which the reservoir is in air-exchanging contact with the exterior surroundings, such that the opening is arranged in the reservoir such that in a determined filling state of the reservoir the ring seal at least partially overrides the opening so that the space supplied with a viscous medium is in fluidic connection with the opening.

A sample dispenser includes a dosing unit, a cradle assembly, and tubing connecting the dosing unit and the cradle assembly. The dosing unit is configured to dispense sampling amounts of a flowable substance and includes a nozzle and a mechanical pump communicating with the nozzle. The cradle assembly includes a priming cradle configured to hold a compressible container of the flowable substance and to force the flowable substance out of the compressible container by applying a compressive force to the compressible container. The tubing allows communication of the flowable substance between the compressible container and the pump.

A paint cartridge includes a housing and a piston slidably disposed within a cavity in the housing to divide the cavity into a paint chamber and a solvent chamber. A valve assembly extends through an aperture in the piston to selectively put the paint chamber in fluid communication with the solvent chamber. A solvent inlet provides solvent to the solvent chamber to move the piston. Movement of the piston discharges paint from the paint chamber through the paint outlet.
