Beschreibung
Zusammenfassung:	A valve assembly comprising a housing having a cavity and including a port forming an opening in the cavity, and a piezoelectric assembly disposed at least partially in the cavity. The piezoelectric assembly comprises an elongated piezoelectric layer, a sealing pad, and an electrical contact. The electrical contact is configured to receive a voltage signal, and when the piezoelectric assembly receives the voltage signal at the electrical contact the piezoelectric layer deforms to cause the sealing pad to selectively seal or unseal the port.
