摘要：
An eccentric pump with lock valve and with bidirectional rotational operation has an inner slide member (8) which is arranged between the casing (1) and the circular sealing ring (5), the slide member (8) being sealingly but moveably attached to inner surfaces of the casing (1), and the slide member (8) being rotatable between a first position and a second position, and
the casing (1) has two inlet openings (11,12) and at least one outlet opening (13), and
the slide member (8) has two through bores (9,10), the first through bore (9) is in communication with one inlet opening (11), the second through bore (10) with at least one outlet opening (13), in the first position of the slide member (8), and the first through bore (9) is in communication with at least one outlet opening (13), the second through bore (10) with the other inlet opening (12), in the second position of the slide member (8), and
the pin (7) is fixed to the slide member (8) and is sealingly separating the through bores (9,10) from each other.
Therefore, the eccentric pump can be mounted directly on the force transmitting shaft of the drive and the shaft can rotate on both direction without stopping the liquid discharge
