Title: A RELIEF VALVE AND A HOSE DEVICE FOR DUST COLLECTORS, A DUST COLLECTOR AND A METHOD FOR OPERATING A DUST COLLECTOR
Abstract:
The invention relates to a relief valve (100) for portable, industrial dust collectors. It has actuating means (102, 104) for actuating the valve (100) between a closed position and an open position. According to the invention, the valve further includes retaining means (107) for maintaining the valve in the open position. The invention also relates to a hose device for a cleaner of a dust collector a dust collector. The hose device is arranged such that it covers the bottom of the grid means in the cleaner when the dust collector operates and falls down when the vacuum in the dust collector is released. The invention further relates to a cleaner, to a dust collector, to a grinding machine and to a method for operating a dust collector. These are in conjunction with the relief valve and/or the hose device. The invention also relates to a dust collector with cleaner means (1, 2), a relief valve (100, 400) and an inlet valve (12) and synchronization means arranged to govern that the actuation of the inlet valve (100, 400) is synchronized with actuation of the relief valve (12).
