Vacuum sewer system comprising a source of sewage (101), sewer piping (102), a discharge valve (103) between the source of sewage and the sewer piping, means (104) for generating partial vacuum in the sewer piping, and a control means for controlling the operation of the discharge valve. The control means comprises a control mechanism (105) with a body part defining a series of chambers including a first end chamber and a second end chamber, wherein the first end chambers is provided with an activating means (106). The body part (12) is provided with a first port (8) for communication with a source of vacuum (102), a second port (9) for communication with the discharge valve (103) and a third port (10) for communication with an aeration means. The activating means (106) is in connection with a first valve means operating in cooperation with a second valve means, which is displaceable between a first position, providing communication between the second port (9) and the third port (10), and a second position, closing the communication between the second port (9) and the third port (10).

The invention claimed is: 1. Vacuum sewer system comprising a source of sewage, sewer piping, a discharge valve between the source of sewage and the sewer piping, means for generating partial vacuum in the sewer piping, and a control means for controlling the operation of the discharge valve, the control means comprising a control mechanism with a body part defining a series of chambers including a first end chamber and a second end chamber, wherein the first end chamber is provided with an activating means, and the body part is provided with a first port for communication with a source of vacuum, a second port for communication with the discharge valve, a third port for communication with an aeration means, a first valve means, and a second valve means whereby the activating means is in connection with the first valve means provided with an engagement means, which engagement means is arranged for releasable engagement with the second valve means which is displaceable between a first position, providing communication between the second port and the third port, and a second position, closing the communication between the second port and the third port, wherein the vacuum sewer system further comprises a rinse water arrangement comprising a rinse water valve, wherein the control mechanism is arranged to control the operation of the rinse water valve through a fourth port in the body part of the control unit, and wherein the activating means is arranged to be pressed so that when it is pressed the first valve means with the engagement means is pushed forward so that the second valve means moves forward to its second position for creating a vacuum connection between the first port, the second port and the fourth port. 2. Vacuum sewer system according to claim 1, wherein the rinse water arrangement further comprises a rinse water supply and a rinse water distribution means. 3. Vacuum sewer system according to claim 1, wherein the engagement means comprises a suction cup. 4. Control means for a vacuum sewer system comprising a control mechanism with a body part defining a series of chambers including a first end chamber and a second end chamber, wherein the first end chamber is provided with an activating means, and the body part is provided with a first port for communication with a source of vacuum, a second port for communication with a discharge valve, a third port for communication with an aeration means, a first valve means, and a second valve means, whereby the activating means is in connection with the first valve means provided with an engagement means, which engagement means is arranged for releasable engagement with the second valve means, which is displaceable between a first position, providing fluid communication between the second port and the third port, and a second position, closing the communication between the second port and the third port, wherein the body part of the control mechanism further is provided with a fourth port in communication with a rinse water valve, and wherein the activating means is arranged to be pressed so that when it is pressed the first valve means with the engagement means is pushed forward so that the second valve means moves forward to its second position for creating a vacuum connection between the first port, the second port and the fourth port. 5. Control means according to claim 4, wherein the series of chambers comprises a first chamber, which constitutes the first end chamber, a second chamber, a third chamber and a fourth chamber, which constitutes the second end chamber, wherein the first valve means is arranged for opening and closing communication between the first chamber and the second chamber wherein the second valve means is arranged for opening and closing communication between the third chamber and the fourth chamber, wherein the first port is in communication with the third chamber and wherein the second port, the third port and the fourth port are arranged in the fourth chamber. 6. Control means according to claim 5, wherein the first valve means further comprises a first valve stem and a first valve seat, which separates the first chamber from the second chamber, the engagement means of the first valve means is arranged to engage with a membrane disposed between the second chamber and the third chamber and attached to the second valve means, and wherein the second valve means comprises a second valve stem, a second valve seat, which separates the third chamber and the fourth chamber, and a valve flap. 7. Control means according to claim 6, wherein the first valve stem of the first valve means is provided with a recess which in cooperation with the first valve seat is arranged to provide communication by forming a channel between the first chamber and the second chamber, and in wherein the first chamber is provided with an aeration opening in the side wall of the body part. 8. Control means according to claim 7, wherein the second valve stem is attached to the membrane at one end and is provided with a sealing means at an opposite end, and wherein the sealing means is arranged to engage with the third port at its second position for closing the communication between the second port and the third port. 9. Control means according to claim 8, wherein the second valve stem of the second valve means is provided with a duct arrangement comprising a first duct and a second duct for providing communication between the second chamber and the third chamber. 10. Control means according to claim 5, wherein the engagement means comprises a suction cup.
