摘要： The invention relates to a drive head comprising a housing (12) with two passages (24, 26), which face away from one another, for a rod assembly (10) and a rotary-driven sleeve (30). Said sleeve surrounds a section of the rod assembly (10) and can be driven by a rotating drive. The rod assembly (10) is connected to the sleeve (30) by a coupling (40). A hydrodynamic recoil brake (60, 70) is provided for controlled reduction of the torsion power accumulated in the rod assembly (10). Said recoil brake in the operating mode conveys a fluid stream through a throttle point (90). In order to detect whether torsion power is accumulated in the rod assembly (10) which may present a potential danger, a pressure sensing device (102, 124, 126) is connected to the throttle point (90) and produces a signal if the pressure of the fluid exceeds a predetermined threshold value.

摘要： A vertically reciprocating pump is described, characterised by a piston (8) which has a support (81, 82, 83) including a hub extending downwards and supporting reinforcement legs, the hub having a rod (7, 71, 72) to which it is translatably coupled passing therethrough, and by a valve overlying the support (81, 82, 83), which seals the piston (8) under the weight of the column of liquid above it or allows the passage of liquid when the piston (8) moves down the water column in the drainage pipe (6).

摘要： A continuous rotary to reciprocatory or reciprocatory to rotary motion converter which comprises a pair of wheels (11 and 12) in spaced co-planar relationship to each other and having an endless flexible drive member (14) received over them, a carrier (15) located to both sides of the drive member, said drive member supporting at one location thereon a slider (17) which extends to each side of the drive member, said slider being slidably received on the carrier to extend to each side thereof for movement with the drive member and transverse movement relative to the axis extending between the wheels whereby with movement of the drive member over the wheels said carrier reciprocates between said wheels and said slider reciprocates transversely on the carrier, support means (18) being provided to support the slider at both sides of the drive member from the carrier continuously throughout movement of the carrier.

摘要： A submersible positive-displacement pump comprises a pump housing (10A/10B) having an inlet (11) at its lower portion and an outlet (17-19) at its upper portion, a variable-volume pump chamber (21) which is provided at the lower portion (10A) of the pump housing and communicates with the inlet through an annular passage (29) having a one-way inlet valve (23) and communicating with the outlet through an opening (20) controlled by a one-way outlet valve (30). A displacement member (27) below the pump chamber (21) is connected with a lifting member (28) which extends upwardly from the pump housing and is connected to a driving device. By means of the lifting member the displacement member can be reciprocated vertically for reducing and increasing the volume of the pump chamber. The pump chamber (21) is defined partly by a circumferentially extending pump housing wall (22) and partly by a sealing coolar (23) which bridges the annular passage (29) and one circumferential end of which is movable in the pump chamber towards and away from the pump housing wall (22) in order to open and close the passage under the influence of a pressure differential between the pump chamber (21) and the inlet (11).
