HOUSING FOR HYDRAULIC DEVICE, DUPLEX HYDRAULIC PUMP AND METHOD OF REVERSING SENSE OF ROTATION OF MULTIPISTON HYDRAULIC DEVICE AND DUPLEX DEVICE

摘要

FIELD: manufacture of pumps. SUBSTANCE: housing 10 of hydraulic device, for example duplex pump has many rotor groups rotating in one direction about common axis 100 by means of source of rotation energy; housing has two opposite end walls 18 and 20 which are perpendicular to common axis 100. Continuous lateral wall 22 connecting walls 18 and 20 and at least two holes 36 and 38 in lateral wall 22 which are used for mounting the rotor groups in housing 10. Housing 10 may contain first flange 24 on one of end walls 18 which is used for securing the housing to rotation energy source. Second flange 26 may be located on other end wall 20; this is used for securing auxiliary pump 104 to main hydraulic device. alternative version provides for reversing the sense of rotation of DUPLEX pump by attachment to other end of housing with no change in internal components, provided flanges 26 and 24 have similar sizes. EFFECT: enhanced reliability.
