Abstract: The arrangement for controlling the flow of laden gases is arranged upstream of an oil separation system and is provided with a check valve, a bypass valve and a stationary segment. The check valve is at least partially movable so as to define a first passage for a forward first flow direction in the event of positive pressure, while the bypass valve is moved rearward by negative pressure so as to clear a second passage for a second, opposite, flow direction. The stationary segment forms a seating surface for the bypass valve. The bypass valve, urged against the seating surface by an elastic biasing member, forms a seat for the check valve. In the event of sufficient negative pressure, the two valves are moved rearward together despite the biasing member and work together to redirect and guide the flow along an escape path corresponding to the second passage.

Abstract: A fluid dispenser includes a receptacle (1), a dispenser member (2), and an actuator member (10) for actuating the dispenser member (2) to dispense the fluid selectively. The actuator member (10) is movable between a rest position and an actuation position for actuating the dispenser member (2), and includes a body portion (11) and a fluid expulsion portion (12) provided with an outlet orifice (13), the fluid expulsion portion (12) being movable relative to the body portion (11) between a locking position in which it prevents the actuator member (10) from moving towards its actuation position, and an in-use position in which it allows the actuator member (10) to move towards its actuation position.
