Abstract: A beverage cask or container 1 has a bung hole outlet housing 2 within which is located a body 4 carrying a liquid extractor tube 9 and a valve means 17,18,19 which cooperates with a top fitting (not shown) to open passageways for introduction of gas A and extraction of liquid B. The body 4 and valve means is retained by a top plate 15 of which the marginal edge portions 16 have been deformed to form a "clench" around the flared top 3 of the housing 2. The clenched top plate forms the sole means of retaining the valve and body assembly in position. The dimensions of the clenched plate 15 are such that the top fitting (not shown) may be directly coupled therewith and the plate further forms an integral constructional part of the valve means being a seating surface for seal 17. The arragement provides security as it is necessary to cut-away the plate 15 to gain access to the container but nevertheless the plate can be fitted and removed easily using appropriate equipment. The need for providing threading on the outlet 2 to secure body 5 is avoided.

Abstract: In a hydraulic percussive machine with a shuttle valve 19 to control the flow of fluid to and from a drive chamber 14 there are no timing lands on the piston 11 and a seal 25 between the drive and return chambers. This is made possible as a result of a restrictive orifice 24 connected to the shuttle valve of conventional design and a port 22 in the return chamber 15 which is covered and uncovered by the piston 11. When the port 22 is uncovered the shuttle valve 19 moves over under pressure. When the port is covered, pressure leaks through the orifice 24 to that the shuttle valve moves back again.
