METHODS AND COMPOSITIONS FOR INHIBITING CELL DEATH OR ENHANCING CEL PROLIFERATION

摘要

A thermostat assembly (200) includes an actuator portion (106) having a sealed container (126) with an arm (108) protruding therefrom. A retainer plate (118) connects the thermostat assembly (200) to an engine component (104). A bypass valve plate (228) is arranged to sealably engage a bypass valve seat (134) that is formed in another component (102). The bypass valve plate (228) includes a body portion (402) having a central opening (408) and an outer periphery, an inner rim (406) surrounds the central opening (408), an outer rim (404) surrounds the outer periphery, and a plurality of openings (230) are formed in the body portion (402). The plurality of openings (230) is adjacent to an interface between t he body portion (402) and the outer rim (404), such that a bypass pressure-dampening fluid passage is defined through the plurality of openings (230) in the bypass val ve plate (228).
