Patent number: 9334969Abstract: Proposed is a pinch valve (1) which has a hose-like valve element (3), an actuating element (18) arranged on the outer circumference of the valve element (3), and at least one radially movable plunger (33a, 33b) arranged between the actuating element (18) and the valve element (3). On the inner side (39) of the actuating element (18) there is situated at least one actuating surface, which extends in the circumferential direction and at the same time axially and which bears against a plunger (33a, 33b). By way of guide means (28a, 28b), it is ensured that, in the event of rotation of the actuating element (18), the actuating surface slides on the at least one plunger (33a, 33b) and pushes the latter radially inward, because the spacing of the actuating surface to the valve element (3) varies over the longitudinal profile thereof.Type: GrantFiled: March 28, 2012Date of Patent: May 10, 2016Assignee: FESTO AG & CO.

Patent number: 9062798Abstract: A pressure regulating device has a pressure regulating valve with a valve casing and a regulating unit which is movable relative to the former. The regulating unit contains an actuation element which may be moved by a control pressure, and two first and second closing members, each spring-biased in a closed position, which may be switched by the actuation element. The connection between a primary port and a secondary port is controlled by the first closing member. Fixed immovably to the actuation element is a restrictor element which is moved into a restriction position when the actuation element is so positioned that the first closing member is normally moved into its closed position. If, because of a fault, the first closing member is not moved into the closed position, only a very small amount of pressure medium flows to the secondary port, so that consequential damage may be avoided.Type: GrantFiled: November 9, 2012Date of Patent: June 23, 2015Assignee: FESTO AG & CO.
