Hydraulic pump for e.g. aquatic activity zone, to practice e.g. surfing, has pipe for passage of shaft extended from casing opening into distribution channel till support system, where shaft is extended freely through pipe

摘要

The pump (10) has a pump shaft (52), and a casing (46) delimiting a liquid circulation channel (44) with outlet orifice (12). The orifice is directed, so that the liquid escapes from the orifice according to liquid outlet axis (14) inclined relative to a longitudinal axis (22) of the shaft. A support system (64) of the shaft is placed in the channel, and comprises a support structure (66) secured to the casing and a bearing to guide the shaft. A pipe for passage of the shaft is extended from a casing opening (87) into the channel until the system. The shaft is extended freely through the pipe. An independent claim is also included for an aquatic activity zone for implementing a water stream by using a hydraulic pump.
