Title (EN) HYDRAULIC COUPLING DEVICE AND MALE AND FEMALE COUPLING UNITS
(FR) DISPOSITIF D'ACCOUPLEMENT HYDRAULIQUE ET UNITÉS D'ACCOUPLEMENT MÂLE ET FEMELLE
Abstract:
(EN) Amale coupling unit (20) for a hydraulic coupling device (10),comprising a male coupling body (21) comprising a hollow core(21c)comprising a male coupling bodycenteraxis (21') extending in a male coupling bodyextension direction, wherein the male coupling body (21) comprises an inner surface (21b)wherein the male coupling body (21) further comprising a poppet valve device (23) arranged in the hollow core (21c),wherein the poppet valve device (23) comprises a poppet device (24), a guide device (25), and a spring device (26), wherein a first end (26a) of the spring device is supported by the poppet device (24) and a second end (26b) of the spring device (26) is supported by the guide device (25), wherein the poppet device (24) is movable in relation to the guide device (25) along the male coupling body extension direction between an open and closed position upon compression and extension of the spring device (26) respectively, wherein the guide device (25) is locked in the male coupling body extension direction, wherein the inner surface (21b) comprises a thread surface portion (21b1),wherein the guide device (25) comprises an outer surface (25a) comprising a thread surface portion (25a1) configured to engage with the corresponding thread surface portion (21b1) of the inner surface (21b) of the male coupling body (21) for locking the guide portion (25).
(FR) Unité d'accouplement mâle (20) destinée à un dispositif d'accouplement hydraulique (10), comprenant un corps d'accouplement mâle (21) comprenant un noyau creux (21c) comprenant un axe central (21') de corps d'accouplement mâle s'étendant dans une direction d'extension de corps d'accouplement mâle, le corps d'accouplement mâle (21) comprenant une surface intérieure (21b), le corps d'accouplement mâle (21) comprenant en outre un dispositif de soupape-champignon (23) disposé dans le noyau creux (21c), le dispositif de soupape-champignon (23) comprenant un dispositif de champignon (24), un dispositif de guidage (25), et un dispositif de ressort (26), une première extrémité (26a) du dispositif à ressort étant supportée par le dispositif de champignon (24) et une seconde extrémité (26b) du dispositif à ressort (26) étant supportée par le dispositif de guidage (25), le dispositif de champignon (24) étant mobile par rapport au dispositif de guidage (25) le long de la direction d'extension de corps d'accouplement mâle entre une position ouverte et une position fermée lors de la compression et de l'extension du dispositif à ressort (26) respectivement, le dispositif de guidage (25) étant verrouillé dans la direction d'extension de corps d'accouplement mâle, la surface intérieure (21b) comprenant une partie de surface filetée (21b1), le dispositif de guidage (25) comprenant une surface extérieure (25a) comprenant une partie de surface filetée (25a1) conçue pour venir en prise avec la partie de surface filetée correspondante (21b1) de la surface intérieure (21b) du corps d'accouplement mâle (21) pour verrouiller la partie de guidage (25).
