The Pump 76, by way of duct 82, pumps ?rst ?uid to open end of the extension 117’, is provided with a transverse valve '90 of group S and then, by way of valve 91, and member 119 from which extends rod 118. 5 duct '98, to ?tting member 92. The return valve 91 re: The extension 118 co-operates with valve 121 in such mains shut. First ?uid from ?tting ‘member 92 also passes to the hydraulic cylinder 99, where it shifts the piston 100 against the bias of spring 101 and thus permits commu nication between the coffee container 145, the grinder 50 and, also, opens the discharge spout for ground coffee to release a predetermined quantity thereof through the a manner that when extension 118 rises it opens valve 121 by impinging upon the stern 121' thereof and thus compressing spring 122. The transverse member 119 co operates, at one side 119a, with arm 123 of a square, sectioned L-lever 123/124 which is pivoted at 125. The arm 124 of the L-lever is arranged to be connectable with lever 94 which latter regulates valve group S. When the ?tting 49 to a strainer which is located at station I. arm 124 is connected to lever 94 it holds the latter in a The arrangement is such that the predetermined quan position such that the spring 97 is compressed. When 15 tities of ?rst ?uid and coffee are so metered that as soon spring 97 is compressed, valve 90 is open and valve 91 as'the strainer in station I is ?lled with coffee, the ex is closed. A second L-lever 126/127, pivoted at 128, is tension 65, integral with piston 63 of cylinder 62, receives provided adjacent the extension 118 and the arm 127 an impulse by the pressurized ?rst ?uid fed to cylinder thereof is arranged to abut the lever 94 when the spring 62 through ?tting member 92.

A spring 136 Within cylinder 133 25 The ?oating ?ange 108 of cylinder 62 has now reached normally holds the piston at the upper end of the cylin the position indicated in FIG. 11 in dotted line and der 133. Above the piston 137 is a chamber 133' con nected by means of a conduit 133a to the chamber 23a of cylinder 23. The cylinder 133 thus functions as a pressostat. thus the lever 105 has pivoted on pivot 106 and will keep an open valve 102. Pressure on piston 23 is there fore maintained . 30 The arm 130 of the lever 129/130 is arranged to be connectable With a lever 138 which latter is pivotally mounted on a member 132 which is secured to stem, 134 in a position in which it can cooperate with lever 85. The lever 85 serves to regulate the group of valves R. When the lever 85 is to be moved from its normal posi tion in which valve 79 is closed and 83 open, to a posi tion in which valve 79 is open and valve 83 is closed, the lever system 129/130, 138 is moved by the member 119. Since pressure remains on piston 23, ?rst ?uid from pump 76 will cause said piston 23 to lift against the pressure of spring 24 and the strainer 36 will be carried ‘toward and held tightly against gasket 7 which surrounds spray head 6. _ The pressure generated in cylinder 23 is transmitted via chamber 133' piston 137 of cylinder 133 by duct 133a. Piston 137 thus slides, in cylinder 133 (the pressostat) against the pressure of spring of spring 136 and thus the member 132, which is integral with the stem 134, also is 40 moved. Movement of member 132 causes small lever 138 ' A spring 139 is inserted between arm 129 and an abut ment 140 on member 132. The spring normally holds the lever 130 in abutment with the lever 138 as shown in to bear against lever ‘85, rotating same around pivot 86 and thus regulating group of valves R in an anticlockwise manner; Movement of lever 85 overcomes the bias of spring 88. The lever 85 is held in the position just referred to until such time as it becomes disengaged by the lever the lever 94 and substantially‘below the spring 97. When 138 in a manner disclosed below, that is ‘in response to the coil of the solenoid is energized by the insertion of the movement of member 119. a coin into the device D, the core 141' is moved to oper When the conditions just referred to apply, valve 79 is ate the valve group S. open and 83 is shut. Pressurized ?rst ?uid from pump 76 The coffee making machine according to the invention 50 now passes to cylinder 44 by way of duct 82, valve '79, operates in the following manner: ~ ' the upper end of valve 83 and conduit 82a.‘Since valve A coin is dropped into the slot 150 and, assuming the 83 is closed, ?rst ?uid cannot return to tank 78.
