The invention relates to a device (2) for sealing and evacuating or applying gas pressure to a paste-like liquid in a container, the interior chamber thereof having a cylindrical inner contour (12). Said device comprises: a seal (8) which is arranged on a circumference of the device (2) and is adapted to be inserted into the cylindrical inner contour (12) of a container in order to seal the circumference of said container, and which delimits the exterior (18) of the device (2) from the interior (20) of the device; a connection device (22) which is arranged on the exterior (18) of the device (2) and which is configured for connecting an evacuation pump; and an open-pored, porous wall (24) in the interior of the device (2), said wall having a conduit connection (25) to the connection device (22).

The liquid material ejector has a liquid material supply port through which the liquid material is supplied, a nozzle for ejecting the liquid material, a valve block having a metering bore to be filled with the ejected liquid material and a liquid material supply channel communicating with the liquid material supply port, a selector valve having a first channel for allowing communication between the metering bore and the liquid material supply channel and a second channel for allowing communication between the metering bore and the nozzle, a plunger advancing and retracting in the metering bore, a plunger driving section for driving the plunger, a valve driving section for driving the selector valve, and a transmission section for transmitting driving power from the valve driving section to the selector valve. The plunger driving section, the valve driving section, and the valve block are arranged successively in the longitudinal direction.

A feeding device for a flowable material is provided with a platen housed in a container containing the flowable material, a cylindrical ram attached to the platen, a pump that reciprocates a piston housed in the ram to suck up the flowable material in the container and a determination device configured to determine a replacement time of the container based on a change in a moving speed of the piston.

An LP gas evacuation system for evacuating LP gas from a vehicle fuel tank includes an inlet port for connection to an excess flow valve associated with the vehicle fuel tank to receive LP gas from the vehicle fuel tank, an outlet port for connection to a storage tank, and a pump coupled between the inlet port and the outlet port. The pump is operable to pump the LP gas from the vehicle fuel tank via the inlet port to the storage tank via the outlet port. The pump is a pneumatically driven displacement pump that can effectively pump both liquid phase LP gas and gas phase LP gas. The pump has seals formed from a material substantially resistant to degradation by contact with the LP gas. The LP gas evacuation system further includes a pneumatic pressure regulator configured to receive a supply of compressed air and to provide compressed air at a desired pressure to the pump. A housing of the evacuation system has a control panel including a switch to selectively supply the compressed air to the pump, pressure gauges to display LP gas pressure at the inlet port and the outlet port, and a sight glass coupled between the pump and the outlet port to permit visual inspection of the LP gas being transferred from the pump to the storage tank.

A cryogenic-fluid compression apparatus having a compression chamber, an intake system, a piston, a discharge orifice in communication with the compression chamber and designed to enable the egress of compressed fluid, the piston comprising a tubular portion mounted about a static central guide connected to the static structure, the apparatus having a sealing system formed between the central guide and the tubular portion of the piston, the compression chamber being delimited by the tubular portion of the piston and a terminal end of the central guide, the central guide being connected to the static structure via a support part received in a longitudinal opening formed in the body of the piston and enabling the relative longitudinal sliding of the piston about the support part. The invention also relates to a filling station comprising such an apparatus.
