A valve has a housing and a component movable within the housing. The housing has first, second, third and fourth ports formed in it. The movable component has a first passageway formed in it. Movement of the movable component within the housing selectively connects the first port through the first passageway to the second port. The movable component is selectively movable to disconnect the first port and second port and to connect the second port through the first passageway to the third port. A second passageway is defined between the housing and the movable component. The fourth port is connected to the second passageway.
A valve having a housing and a component movable within the housing, the housing having first, second, third, fourth, and fifth ports formed in it, the movable component having a first passageway formed in it, a first orientation of the movable component within the housing selectively connecting the first port through the first passageway to the second port, a second orientation of the movable component within the housing selectively connecting the second port through the first passageway to the third port, and a second passageway defined between the housing and the movable component, the fourth port and fifth port connected to the second passageway at both the first and second orientations of the movable component, the fourth port comprising a first slot shaped opening facing the movable component.
A valve having a first movable valve component and a first valve housing, a first passageway defined through the first movable component, first, second, third and fourth ports through the first valve housing, the first movable component having a first orientation in which the first passageway couples the first port to the second port and a second orientation in which the first passageway does not couple the first port to the second port, and a second passageway defined between the first movable component and the first valve housing, the second passageway coupling the third port to the fourth port at both the first and second orientations, the third port comprising a first slot shaped opening facing the movable component.
