Claims22
A rapid coupling system (100) for establishing a connection of at least two pressurised lines (Lx) with a first coupling element which can be connected with a second coupling element in a pressure sealed manner, characterised by an external pressure relief unit (70) that is allocated to the rapid coupling system (100) which pressure relief unit can be connected with at least one of the pressurised lines (Lx) via at least one pressure relief connection (52).
A rapid coupling system according to any one of the preceding claims, characterised in that an operating mechanism for the pressure relief unit (70) comprises a journal (42) with which the control plunger (44) cooperates and which is particularly arranged on the same axis with the control plunger (44).
A rapid coupling system according to any one of the preceding claims, characterised in that the pressure relief unit (70) comprises the control unit (10), the pressure relief connection (52), at least one pressure relief valve system (50), at least one pressure relief chamber (46) and at least one pressure relief line (48).
A rapid coupling system according to any one of the preceding claims, characterised in that at least one pressure relief valve system (50) comprises at least one valve spring (72) and at least one valve ball (74).
A rapid coupling system according to any one of the preceding claims, characterised in that each pressure relief connection (52) is allocated at least one pressure relief valve system (50).
A rapid coupling system according to any one of the preceding claims, characterised in that several pressure relief valve systems (50) of the pressure relief unit (70) are conducted towards at least one pressure relief chamber (46) and at least one pressure relief line (48).
A rapid coupling system according to any one of the preceding claims, characterised in that the pressure relief valve system (50) is arranged radially to the control plunger (44).
A rapid coupling system according to any one of the preceding claims, characterised in that the control unit (10) and the pressure relief chamber (46) with its pressure relief line (48) are arranged on the same axis.
A rapid coupling system according to any one of the preceding claims, characterised in that the plug element (12) comprises a valve (30) between a channel (68) and a chamber (34) and a sealing unit (91) between a tappet (28) and a housing (22).
A rapid coupling system according to any one of the preceding claims, characterised in that the socket element (14) comprises a sealing unit (38) between a sliding element (26) and a housing element (64).
A rapid coupling system according to any one of the preceding claims, characterised in that during a coupling process of the coupling elements (12) and (14), the connecting blocks (16) and (18) are simultaneously displaceable against each other.
A rapid coupling system according to any one of the preceding claims, characterised in that the journal (42) that operates the control plunger (44) opens a passage from the channel (66) in the socket element (14) in a first coupling step, wherein by means of the cam (54) of the control plunger (44) the pressure relief valve (50) towards the pressure relief chamber (46) is opened.
A rapid coupling system according to any one of the preceding claims, characterised in that the valve (30) comprises in a second coupling step a connection between the channel (68) and the pressure relief chamber (46) through the pressure relief valve (56), via the chamber (34), passing by the sealing unit (88) through the channel (66), via the pressure relief connection (52) through the pressure relief valve system (50), wherein by means of the cam (54) of the control plunger (44) the pressure relief valve system (50) towards the pressure relief chamber (46) and the adjacent pressure relief line (48) is kept open to enable a pressure compensation inside the rapid coupling system (100).
A rapid coupling system according to any one of the preceding claims, characterised in that the journal (42) displaces the control plunger (44) axially in a third coupling step thus connecting the chamber (34) and the channel (68) with each other while simultaneously releasing the valve (30), while the cam (54) of the control plunger (44) keeps open the pressure relief valve system (50) and releases the pressure relief connection (52) towards the pressure relief chamber (46) and the adjacent pressure relief line (48) to enable a pressure compensation inside the rapid coupling system (100).
A rapid coupling system according to any one of the preceding claims, characterised in that in a fourth coupling step due to a further axial displacement of the journal (42) the control plunger (44) is pushed completely into the pressure relief valve system (50), wherein the cam (54) of the control plunger (44) is passing by the pressure relief valve system (50) and the pressure relief connection (52) towards the pressure relief chamber (46) and the adjacent pressure relief line (48) in the rapid coupling system (100) is closed.
A rapid coupling system according to claim 22, characterised in that the cam (54) releases the valve ball (74) thus causing the pressure relief valve system (50) subject to the action of the valve spring (72) to travel to its closing position.
