Disclosed is a disposable filter capsule apparatus that incorporates integral quick connect components and check valves to facilitate assembly to, and dis-assembly from, larger assemblies and apparatus. The quick connect elements and valves are configured to eliminate the need for auxiliary sealing elements, e.g., o-rings and valve springs so as to prevent unwanted reactions with fluids and/or gases flowing through the capsules, and to further prevent the disposal of expensive re-usable elements in the disposable capsules.

The invention relates to a nozzle, which has a main valve arranged in a channel, a coupling device (30) for producing a connection between the nozzle and the connecting piece (15), and an actuating apparatus (17) for actuating the coupling device and the main valve. The actuating apparatus comprises a manual lever (11), which is movable between a closed position and an open position. The actuating apparatus is designed to convert a movement of the manual lever in a region between the closed position and the open position to a temporally offset actuation of the coupling device and of the main valve. A coupling joint (20) connected to the manual lever is connected via operative connections to the coupling device having the main valve. The operative connections for the coupling joint form a guide such that the coupling joint is caused to rotate about a first pivot axis (41) and/or to move in a first direction when the manual lever is activated in a first manual lever region, and that the coupling joint having the manual lever in a second manual lever region is caused to rotate about a second pivot axis (42) and/or to move in a second direction.

The invention relates to a coupling (110) for connecting a compressed air source to an air motor, comprising a housing (116) with a housing channel leading to a compressed air connection (118) and a piston (124) axially adjustable in the housing channel (122) and force-loaded by a spring element (126) having a piston channel (132) which, when the coupling is connected to the air motor, merges into a connecting channel (138) present in a pin element (140) of the air motor. The piston can be adjusted in the direction of the compressed air connection by means of the pin element against the force applied by the spring element. The spring element (126) runs between the compressed air connection (118) and the compressed air connection side area of the piston (124). Radial openings (34, 36, 134, 136), through which compressed air flows, extend from the compressed air connection side area of the piston channel (132). At least one exhaust air channel (160, 162) connected to the air motor extends in the wall of the housing (116) and passes through the wall in the end face of the housing.

This document describes devices and methods for reducing liquid spillage, such as fluid coupling devices that include one or more apertures that reduce spillage when the fluid coupling devices are disconnected. In some embodiments, the one or more apertures are designed with features to increase a level of acceleration that liquid within an internal volume of the fluid coupling devices would need to be exposed to in order to spill from the internal volume via the one or more apertures.
