A vehicle may include an internal combustion engine having a crankcase and a supercharging apparatus, and a crankcase ventilation apparatus having at least one oil-separating apparatus including at least one oil separator. An oil return line may communicate separated oil from the crankcase ventilation apparatus to the crankcase. An ejector pump may be driven via a compressed air flow of the supercharging apparatus and may be configured to generate an underpressure for driving a blow-by gas. The crankcase ventilation apparatus may include a pump control valve configured to at least one of regulate and control the compressed air flow through the ejector pump.

Crankcase ventilation apparatus

A connection device may include an insertion section having an annular outer groove. A housing may be configured to receive the insertion section and a blocking element may be configured to lock the insertion section in the housing. The blocking element may have a band-shaped core and a plurality of teeth arranged adjacent in the peripheral direction along the core. Each of the teeth may include an outer tooth section and an inner tooth section. A core profile may have a core principal direction determined by a maximum diameter. The teeth may have a tooth profile which has a tooth principal direction determined by an inner flank of the teeth lying radially on an interior of the outer tooth section and the core principal direction may be inclined with respect to the tooth principal direction.

Connection device

A coupling unit having at least one tubular section; a casing; at least one detent ring, which is arranged radially between the casing and the at least one tubular section when the at least one tubular section, is inserted in the casing, wherein the at least one detent ring, the casing, and the at least one tubular section are configured to adapt to one another such that the tubular section is inserted axially into the casing in a first relative rotational position of the tubular section and the casing, wherein the tubular section is secured by the detent ring against axial withdrawal, the casing and tubular section can be rotated relative to one another, and wherein for decoupling purposes, the tubular section can be withdrawn axially from the casing in a second relative rotational position of the casing and the tubular section that differs from the first rotational position.
