Abstract: 538,952. Valve gear. STEVENS, A. H. (Eaton Manufacturing Co.). Feb. 17, 1940, No. 3060. [Class 7 (vi)] A hydraulic device for taking up clearance between a rocker and its cam comprises a hollow plunger 1 fitted in a recess in the rocker and containing a sleeve 3 formed with a partition 4 dividing it into upper and lower chambers 5, 6, the upper acting as a reservoir for oil received from a channel 10 in the rocker, and the lower as a pressure chamber connected to the former by a port 8 and a non-return valve 7 opening downwards. Resilient washers 14 may be interposed between the sleeve 3 and the end of the recess, or a spring may be fitted between the head 1a of the plunger and a cap 12 enclosing the valve 7. Air escapes at an orifice 10a. Adjustment of the plunger may be obtained by forming the recess in a plug screwed into the rocker. The whole device is attached to the rocker by a pin 13 passing through enlarged holes 1b in the plunger, so as to allow axial movement; or a pin may pass through a slot or flat in the side of the plunger.

Abstract: The invention relates to a control arrangement for gas exchange in a piston engine adapted between a cam device (5) of a camshaft (4) of the engine (1) and an inlet valve mechanism (6) arranged to open and close the inlet valve (3) in association with a cylinder of the engine, which control arrangement (7) comprises a body part (8), in which a piston device (9) is movably arranged to be in force transmission connection with the camshaft (4) and the valve mechanism (6). The cam device (5) includes a cam profile (5') having a portion (5c) arranged under a base circle (5a) of the cam profile (5'). Said portion (5c) of the cam profile (5') is arranged to control gas exchange through the inlet valve (3), specifically for providing a delay in the closing of the inlet valve (3).

Abstract: An engine roller lifter for use in a valve train of an internal combustion engine according to one example of the present disclosure includes a body and a groove formed in the body. The body has an outer peripheral surface configured for sliding movement in a bore provided in the engine. The bore is supplied by an oil passage communicating therewith. The body defines an axial pocket that receives a plunger therein. The groove is inset from the outer peripheral surface and formed about only a portion of a circumference of the body. The groove defines a first end and a second end. Only a portion of the first and second ends overlap with the oil passage to regulate the amount of oil supplied to the groove from the oil passage.
