Apparatus for intermittent delivery of a fluid under pressure wherein a plunger having a conduit is disposed in a housing for reciprocal, rotary motion and responsive to fluid pressure at the intake end, by means provided in the plunger pops out of the housing and rotates a pre-selected number of degrees. Means are provided to stop both rotary and axial movement simultaneously.

Apparatus for intermittent delivery of a fluid under pressure from a source thereof comprising: a. a hollow cylindrical housing; b. a cylindrical plunger disposed within said housing comprising: (1) a body; (2) means defining a delivery head at one end of said body; and (3) means defining a piston at the other end of said body; c. means defining an axial fluid conduit communicating between the two ends of said body and defining an intake orifice in said piston end and a delivery orifice adapted to direct a flow of fluid under pressure in a selected direction from said head; d. means for reciprocating and incrementally rotating said plunger body within said housing between a ready position wherein said head is flush with an end of said housing and a fluid delivery position wherein said head is extended out of said housing, comprising: (1) means for simultaneously rotating and axially advancing said body responsive to pressure from said source of fluid comprising at least one rotator bore disposed in said body at an angle to the direction of flow of the fluid whereby the fluid pressure will rotate said plunger; (2) means for limiting the length of the axial and rotary travel of said body between a ready position and a delivery position; and (3) means for returning said body to said ready position; and e. means for connecting said intake orifice with a source of fluid under pressure.
