Ein hydraulischer Radialkolbenmotor mit mindestens einem Nockenring (4) und mindestens einem Zylinderblock (6), die relativ zueinander um eine Drehachse D drehbar in einem Gehäuse (2) angeordnet sind, wobei der Zylinderblock (6) mit einer Mehrzahl radial zur Drehachse D angeordneter Kolben (10) versehen ist, die an ihren radial äußeren Enden am Nockenring (4) ablaufende Stürzrollen (12) aufweisen, zeichnet sich durch eine die jeweiligen Winkelstellung zwischen dem Nockenring (4) und dem Zylinderblock (6) erfassende Messvorrichtung (34) aus.
摘要:
The invention relates to a converter for converting mechanical energy into hydraulic energy, and to a robot implementing said converter. The invention can particularly be used in the production of humanoid robots in which autonomy is to be improved. The converter includes a shaft (10) rotated by mechanical energy about an axis (13) relative to a first casing (14), a hub (20) comprising a bore formed about a second axis, wherein the shaft (10) rotates in the bore, the two axes (13) being parallel and a distance between the axes defining an eccentricity (E), and at least two pistons capable of movement in a radial housing of the shaft (10), the piston bearing on the bore. According to the invention, the movement of the piston feeds a hydraulic fluid into two annular grooves of the casing (14), arranged in an arc of a circle about the first axis (13), the hydraulic energy being generated by a pressure difference of the fluid present between the two grooves (40, 41), while the hub (20) is capable of translation along a third axis perpendicular to the first two axes (13) in order to modify the value of the eccentricity (E) between two extreme values, i.e. a positive one and a negative one, so as to generate a pressure inversion of the fluid in the grooves (40, 41), thereby inverting the inlet and discharge roles of the grooves while maintaining the same rotation direction for the shaft (10).

According to one embodiment, a radial fluid device (600, 700) comprises a cylinder block (604, 704), first and second pluralities of pistons, a first cam (622, 632, 642, 652, 662, 732, 742, 752, 762) disposed about the first plurality of radially extending cylinders, and a second cam (622', 632', 642', 652', 662', 732', 742', 752', 762') disposed about the second plurality of radially extending cylinders. The direction of rotation of the second cam (622', 632', 642', 652', 662', 732', 742', 752', 762') is independent of the direction of rotation of the first cam (622, 632, 642, 652, 662, 732, 742, 752, 762).
摘要:
There is described a volumetric pump comprises a housing (3) containing at least one hollow elongated part (2), at least one piston (4) arranged to move back and forth inside said elongated part (2), at least one inlet port (11 ) and at least one outlet port (111) arranged so that a fluid can be sucked through the inlet port (11) into a chamber during an instroke of the piston (4) and expelled from the chamber through the outlet port (111) during an outstroke of said piston (4). The pump further comprises a linearly and/or angularly actuable valve system (5, 5', 5") possessing at least one valve holder (5") mounted on the pump housing (3) such that a surface (7) of the valve holder (5") is held against a part (7') of the housing outer surface. The pump housing (3) comprises at least one through-hole (30) extending from the piston chamber to said part (7') of the housing outer surface. The valve holder (5") contains at least one inlet and/or outlet aperture(s) (31, 31') and is arranged to be actuable linearly and/or rotatably to align alternately the inlet and outlet apertures (31, 31 ') with the through-hole (30) of the housing (3) in order to connect alternately the inlet and outlet ports (11, 11 ') of the volumetric pump with the piston chamber during alternate piston instrokes and outstrokes.
