摘要： An automatic clutch for automotive and other applications employs a control rod to manually control engagement and disengagement of the clutch independently of its speed of rotation, and in one form of invention can be employed in manual start motorcycles to engage the clutch for bumpstarting purposes before the engine is up to speed, and in an alternate form a control rod can be employed in electrically started bikes to lock the clutch against engagement whether or not the engine is up to the speed required for automatic engagement of the clutch. The control rod may either extend through the transmission shaft from one end of the clutch housing or may extend through the opposite end of the clutch housing, and in certain applications the hereinbefore described control rods can be combined to selectively control bumpstarting to manually effect clutch engagement or as a locking mechanism to prevent clutch engagement.

摘要： A centrifugal pump of the hydraulic sealing type has a novel and improved sealing apparatus for establishing a hydraulic seal and limiting the flow of liquid from a pump casing into a reservoir or seal housing at one end of the pump casing, and a valve assembly in the seal housing has a valve member normally urged into engagement with the seal housing to isolate liquid in the seal housing from the casing when the pump is not in operation. When the pump is activated and brought up to speed, centrifugal force-responsive pivot members are operative to move the valve member away from sealed engagement with the seal housing to establish fluid communication between the seal housing and pump casing. The force-responsive pivot members are fully enclosed so as to be completely isolated from the liquid in the seal housing and yet be capable of operating directly in opposition to the resilient or spring-loaded valve to move the valve away from sealed engagement with the seal housing. An expeller ring at one end of the seal housing limits liquid flow into the seal housing when the pump is stopped and removes any liquid in the reservoir into the pump casing when the pump is started.
