Abstract
A tip seal for scroll wraps in a scroll compressor is provided. The tip seal may include surface features to form a tortuous flow path in a seal groove of a scroll wrap. The surface features can help form one or more contraction and/or expansion areas in the tortuous flow path. The tortuous flow path can help provide resistance to fluid flow and help reduce leakage through the seal groove.
