Abstract:

An apparatus for assisting a primary governor device (20) on an engine at certain load conditions or during transient loading is disclosed. The primary governor device has a control arm (12) which is moved by a primary governor spring (15) via a primary governor arm (14). The control arm (12) governs opening and closing of the throttle plate (10) on the carburetor (11). Four embodiments (47, 54, 30 and 78) of the governor assist mechanism are disclosed. The governor assist apparatus has an assist spring (48, 55, 32, 76) operatively connected to the control arm (12). A vacuum capsule (41) actuates the assist spring (48, 55, 32, 76) from the primary governor device (20) according to the vacuum in the intake manifold and load on the engine. The first embodiment or linear mechanism (47) has an assist spring (48), an intermediate link (49), and the diaphragm plunger (40) in linear alignment. The second embodiment or rocker mechanisn (54) interconnects the assist spring (55) and the diaphragm plunger (40) by means of a pivotal arrangement or bell crank (58).
