Drilling apparatus comprises a hollow drill pipe (2) extending through a drill hole (4) to a mud motor (8). The motor (8) drives a compressor (12) through a shaft (14). An annular passageway (16) around the compressor (12) leads to a drill bit (18) having nozzles (20) providing an outlet from the passageway (16). A housing (22) of the compressor (12) provides a passageway (24) for leading fluid through the compressor (12) to emerge through nozzles (26) in the drill bit (18) at increased pressure to assist the drill bit (18).

Bei einer Vorrichtung zur Herstellung eines Gemisches werden mindestens zwei Massen getrennt voneinander dosiert und in einem vorbestimmten Verhältnis miteinander gemischt. Für jede Masse ist mindestens eine Kammer variablen Volumens vorgesehen, die in einem Gehäuse beweglich gelagert ist. In dem Gehäuse ist ein Zulauf und ein Ablauf vorgesehen, die in entsprechenden Stellungen der Kammer in diese münden. Die Kammern weisen flexible Seitenwandungen auf, deren Ebenen senkrecht zur jeweil igen Schubrichtung verlaufen. Die Kammern sind um eine gemeinsame Achse verschwenkbar angeordnet. Jede Kam mer ist außer von den beiden flexiblen Seitenwandungen von Wandungen des Gehäuses sowie einer Nabe begrenzt, die auf einer Welle befestigt ist.

There is disclosed a fluid switching valve that can switch fluid path states among a plurality of fluid paths by a simple configuration. A fluid switching valve including a first elastic tube that delivers a first fluid; a second elastic tube that delivers a second fluid; a third elastic tube having one end connected to the first and second elastic tubes; and a switching member that, by displacing a protruding portion, switches between a first state in which the first elastic tube is constricted and the second fluid is delivered to the third elastic tube, a second state in which the second elastic tube is constricted and the first fluid is delivered to the third elastic tube, a third state in which the first and second elastic tubes are both constricted and introduction of fluid to the third elastic tube is cut off, and a fourth state in which neither the first nor second elastic tube is constricted and both the first and second fluids are delivered to the third elastic tube.
